viper06 power section doc id 022794 rev 1 15/28 7 power section the power section is implemented with an n-channel power mosfet with a breakdown voltage of 800 v min. and a typical r ds(on) of 32 . it includes a sensefet structure to allow virtually lossless current sensing and the thermal sensor. the gate driver of the power mosfet is designed to supply a controlled gate current during both turn-on and turn-off in order to minimize common-mode emi. during uvlo conditions, an internal pull-down circuit holds the gate low in order to ensure that the power mosfet cannot be turned on accidentally. 8 high voltage current generator the high-voltage current generator is supplied by the drain pin. at the first startup of the converter it is enabled when the voltage across the input bulk capacitor reaches the v drain_start threshold, sourcing a i ddch1 current (see table 6 on page 7 ). as the v dd voltage reaches the v ddon threshold, the power section starts switching and the high- voltage current generator is turned off. the viper06 is powered by the energy stored in the v dd capacitor. in a steady-state condition, if the self-biasing function is used, the high-voltage current generator is activated between v ddcson and v ddon (see table 6 on page 7 ), delivering i ddch2 , see table 6 on page 7 to the v dd capacitor during the mosfet off-time (see figure 21 ). the device can also be supplied through the auxiliary winding in which case the high- voltage current source is disabled during steady-state operation, provided that vdd is above v ddcson . at converter power-down, the v dd voltage drops and the converter activity stops as it falls below the v ddoff threshold (see table 6 on page 7 ). figure 21. power-on and power-off i dd v dd v drain v ddon t t t t v in v drain_start t t power-on power-off normal operation regulation is lost here v in < v drain_start hv startup is no more activated with internal self-supply without internal self-supply v ddcson v ddoff i ddch1 i ddch2
oscillator viper06 16/28 doc id 022794 rev 1 9 oscillator the switching frequency is internally fixed at 30 khz or 60 khz or 115 khz (respectively part numbers viper06xx, viper06lx and viper06hx). the switching frequency is modulated by approximately 3 khz (30 khz version) or 4 khz (60 khz version) or 8 khz (115 khz version) at 230 hz (typical) rate, so that the resulting spread spectrum action distributes the energy of each harmonic of the switching frequency over a number of sideband harmonics having the same energy on the whole, but smaller amplitudes. 10 soft startup during the converter?s startup phase, the soft-start function progressively increases the cycle-by-cycle drain current limit, up to the default value i dlim . in this way the drain current is further limited and the output voltage is progressively increased, reducing the stress on the secondary diode. the soft-start time is internally fixed to t ss , see typical value in table 7 on page 8 , and the function is activated for any attempt of converter startup and after a fault event. this function helps prevent saturation of the transformer during startup and short-circuit. 11 adjustable current limit set point the viper06 includes a current-mode pwm controller. the drain current is sensed cycle- by-cycle through the integrated resistor r sense and the voltage is applied to the non- inverting input of the pwm comparator, see figure 2 on page 4 . as soon as the sensed voltage is equal to the voltage derived from the comp pin, the power mosfet is switched off. in parallel with the pwm operations, the comparator ocp, see figure 2 on page 4 , checks the level of the drain current and switches off the power mosfet in case the current is higher than the threshold i dlim , see table 7 on page 8 . the level of the drain current limit i dlim can be reduced using a resistor r lim connected between the lim and gnd pins. current is sunk from the lim pin through the resistor r lim and the setup of i dlim depends on the level of this current. the relation between i dlim and r lim is shown in figure 13 on page 11 . when the lim pin is left open or if r lim has a high value (i.e. > 80 k ), the current limit is fixed to its default value, i dlim , as given in table 7 on page 8 .
viper06 fb pin and comp pin doc id 022794 rev 1 17/28 12 fb pin and comp pin the device can be used both in non-isolated and isolated topology. in non-isolated topology, the feedback signal from the output voltage is applied directly to the fb pin as the inverting input of the internal error amplifier having the reference voltage, v ref_fb, see ta bl e 7 o n page 8 . the output of the error amplifier sources and sinks the current, i comp , respectively to and from the compensation network connected on the comp pin. this signal is then compared in the pwm comparator with the signal coming from the sensefet in order to switch off the power mosfet on a cycle-by-cycle basis. see the figure 2 on page 4 and the figure 22 . when the power supply output voltage is equal to the error amplifier reference voltage, v ref_fb , a single resistor has to be connected from the output to the fb pin. for higher output voltages the external resistor divider is needed. if the voltage on the fb pin is accidentally left floating, an internal pull-up protects the controller. the output of the error amplifier is externally accessible through the comp pin and it?s used for the loop compensation, usually an rc network. as shown in figure 22 , in case of an isolated power supply, the internal error amplifier has to be disabled (fb pin shorted to gnd). in this case an internal resistor is connected between an internal reference voltage and the comp pin, see figure 22 . the current loop has to be closed on the comp pin through the opto-transistor in parallel with the compensation network. the v comp dynamic range is between v compl and v comph shown in figure 23 on page 18 . when the voltage v comp drops below the voltage threshold v compl , the converter enters burst mode, see section 13 on page 18 . when the voltage v comp rises above the v comph threshold, the peak drain current, as well as the deliverable output power, will reach its limit. figure 22. feedback circuit fb comp without isolation: switch open & e/a enabled with isolation: switch closed & e/a disabled no isolation v out + - pwm stop from r sense r isolation r l nr sw v ref r comp + - e/a bus + - to pwm v compl r h v ref_fb
burst mode viper06 18/28 doc id 022794 rev 1 figure 23. comp pin voltage versus i drain 13 burst mode when the voltage v comp drops below the threshold, v compl , the power mosfet is kept in the off state and the consumption is reduced to the i dd0 current, as reported on ta b l e 6 o n page 7 . in reaction to the loss of energy, the v comp voltage increases and as soon as it exceeds the threshold v compl + v compl_hys , the converter starts switching again with a level of consumption equal to the i dd1 current. this on-off operation mode, referred to as ?burst mode? and shown in figure 24 on page 18 , reduces the average frequency, which can go down even to a few hundreds hertz, thus minimizing all frequency-related losses and making it easier to comply with energy-saving regulations. during burst mode, the drain current limit is reduced to the value i dlim_bm (given in table 7 on page 8 ) in order to avoid the audible noise issue. figure 24. load-dependent operating modes: timing waveforms am01095v1 v comph v compl i dlim_bm i dlim i drain v comp time time time v comp v compl +v compl_hys v compl i dd1 i dd0 i dd i drain i dlim_bm burst mode
viper06 automatic auto-restart after overload or short-circuit doc id 022794 rev 1 19/28 14 automatic auto-restart after overload or short-circuit the overload protection is implemented automatically using the integrated up-down counter. every cycle, it is incremented or decremented depending upon the current logic detection of the limit condition or not. the limit condition is the peak drain current, i dlim , given in ta bl e 7 on page 8 or the one set by the user through the r lim resistor, shown in figure 13 on page 11 . after the reset of the counter, if the peak drain current is continuously equal to the level i dlim , the counter will be incremented until the fixed time, t ovl , at which point the power mosfet switch on will be disabled. it will be activated again through the soft-start after the t restart time (see figure 25 and figure 26 on page 19 ) and the time values mentioned in table 7 on page 8 . for overload or short-circuit events, the power mosfet switching will be stopped after a period of time dependent upon the counter with a maximum equal to t ovl . the protection sequence continues until the overload condition is removed, see figure 25 and figure 26 . this protection ensures a low repetition rate of restart attempts of the converter, so that it works safely with extremely low power throughput and avoids overheating the ic in case of repeated overload events. if the overload is removed before the protection tripping, the counter will be decremented cycle-by-cycle down to zero and the ic will not be stopped. figure 25. timing diagram: olp sequence (ic externally biased) figure 26. timing diagram: olp sequence (ic internally biased) time time v dd v ddon v ddcson i drain i dlim_bm t 1 * * the time t 1 can be lower or equal to the time t ovl t restart t ss t ovl t restart t ss t ovl t restart t ss short circuit occurs here short circuit removed here time time v dd v ddon v ddcson i drain i dlim_bm t 1 * * the time t 1 can be lower than or equal to the time t ovl t restart t ss t ovl t restart t ss t ovl t restart t ss short circuit occurs here short circuit removed here
open-loop failure protection viper06 20/28 doc id 022794 rev 1 15 open-loop failure protection if the power supply has been designed using flyback topology and the viper06 is supplied by an auxiliary winding, as shown in figure 27 and figure 28 on page 21 , the converter is protected against feedback loop failure or accidental disconnections of the winding. the following description is applicable for the schematics of figure 27 and figure 28 on page 21 , respectively the non-isolated flyback and the isolated flyback. if r h is open or r l is shorted, the viper06 works at its drain current limitation. the output voltage, v out , will increase as does the auxiliary voltage, v aux , which is coupled with the output through the secondary-to-auxiliary turns ratio. as the auxiliary voltage increases up to the internal v dd active clamp, v ddclamp (the value is given in table 7 on page 8 ) and the clamp current injected on the vdd pin exceeds the latch threshold, i ddol (the value is given in table 7 on page 8 ), a fault signal is internally generated. in order to distinguish an actual malfunction from a bad auxiliary winding design, both the above conditions (drain current equal to the drain current limitation and current higher than i ddol through the vdd clamp) have to be verified to reveal the fault. if r l is open or r h is shorted, the output voltage, v out , will be clamped to the reference voltage v ref_fb (for non-isolated flyback) or to the external tl voltage reference (for isolated flyback). figure 27. fb pin connection for non-isolated flyback v compl d aux nr fb vdd v aux comp + - to pwm r l + - e/a r h r r aux c vdd v out r s v ref_fb from r sense bus + - pwm stop c s c p
