fscm0465r green mode fairchild power switch (fps?) ? 2006 fairchild semiconductor corporation www.fairchildsemi.com fscm0465r rev. 1.0.1 10 functional description 1. startup : figure 16 shows the typical startup circuit and transformer auxiliary winding for the fscm0465r application. before the fscm 0465r begins switching, it consumes only startup current (typically 20a) and the current supplied from the dc link supply current consumed by the fps (i cc ) and charges the external capacitor (c a ) connected to the v cc pin. when v cc reaches start voltage of 12v (v start ), the fscm0465r begins switching and the current consumed by the fscm0465r increases to 2.5ma. then the fscm0465r continues its normal switch ing operation and the power required for this device is supplied from the transformer auxiliary winding, unless v cc drops below the stop voltage of 8v (v stop ). to guarantee the stable operation of the control ic, v cc has under-voltage lockout (uvlo) with 4v hysteresis. figure 17 shows the relationship between the current consumed by the fps (i cc ) and the supply voltage (v cc ). figure 16. startup circuit figure 17. relation between operating supply current and v cc voltage the minimum current supplied through the startup resistor is given by: where v line min is the minimum input voltage, v start is the start voltage (12v) and r str is the startup resistor. the startup resistor should be chosen so that i sup min is larger than the maximum startup current (40a). if not, v cc can not be charged to the start voltage and fps fails to start. 2. feedback control : the fscm0465r employs current mode control, as s hown in figure 18. an opto- coupler (such as the h11a817a) and a shunt regulator (such as the ka431) are typically used to implement the feedback network. comparing the feedback voltage with the voltage across the rsense resistor makes it possible to control the switching duty cycle. when the reference pin voltage of the ka431 exceeds the internal reference voltage of 2.5v, the h11a817a led current increases, pulling down the feedback voltage and reducing the duty cycle. this event typically happens when the input voltage is increased or the output load is decreased. 2.1 pulse-by-pulse current limit : because current mode control is employed, the peak current through the sensefet is determined by the inverting input of the pwm comparator (vfb*) as shown in figure 18. when the current through the opto-transistor is zero and the current limit pin (#5) is left floating, the feedback current source (i fb ) of 0.9ma flows only through the internal resistor (r+2.5r=2.8k). in th is case, the cathode voltage of diode d2 and the peak drain current have maximum values of 2.5v and 2.5a, respectively. the pulse-by- pulse current limit can be ad justed using a resistor to gnd on the current limit pin (#5). the current limit level using an external resistor (r lim ) is given by: figure 18. pulse width modulation (pwm) circuit fscm0465r rstr v cc ca da i sup ac line (v line min - v line max ) c dc i cc fscm0465r rev. 00 i cc v cc vstop=8v 3ma vstart=12v vz power up power down 25 a fscm0465r rev. 00 () min min sup line star t str 1 ivv r 2 =? ? ?

fscm0465r green mode fairchild power switch (fps?) ? 2006 fairchild semiconductor corporation www.fairchildsemi.com fscm0465r rev. 1.0.1 11 2.2 constant power limit circuit : due to the circuit delay of fps, the pulse-by-p ulse limit current increases a little bit when the input voltage increases. this means unwanted excessive power is delivered to the secondary side. to compensate, the auxiliary power compensation network in figure 19 can be used. r lim can adjust pulse- by-pulse current by absorbing internal current source (i fb : typical value is 0.9ma), depending on the ratio between resistors. with the suggested compensation circuit, additional current from i fb is absorbed more proportionally to the input voltage (v dc ) and achieves constant power in wide input range. choose r lim for proper current to the applicat ion, then check the pulse- by-pulse current difference between minimum and maximum input voltage. to el iminate the difference (to gain constant power), r y can be calculated by: where, i lim _spec is the limit current stated on the specification; n a and n p are the number of turns for v cc and primary side, respectively; i fb is the internal current source at feedback pin with a typical value of 0.9ma; and i lim_comp is the current difference which must be eliminated. in case of capacitor in the circuit 1f, 100v is good choice for all applications. figure 19. constant power limit circuit 2.3 leading edge blanking (leb) : at the instant the internal sensefet is turned on, a high-current spike through the sensefet usually occurs, caused by primary-side capacitance a nd secondary-side rectifier reverse recovery. excessive voltage across the rsense resistor can lead to incorrect feedback operation in the current mode pwm control. to counter this effect, the fscm0465r employs a leading edge blanking (leb) circuit. this circuit inhibits the pwm comparator for a short time after the sensefet is turned on. 3. protection circuit : the fscm0465r has several self-protective functions, such as overload protection (olp), over-voltage protection (ovp) and thermal shutdown (tsd). because t hese protection circuits are fully integrated into the ic without external components, the reliability is improved without increasing cost. once the fault condition occurs, switching is terminated and the sensefet remains off. this causes v cc to fall. when v cc reaches the uvlo stop voltage of 8v, the current consumed by the fscm0465r decreases to the startup current (typically 20a) and the current supplied from the dc link charges the external capacitor (c a ) connected to the v cc pin. when v cc reaches the start voltage of 12v, the fscm0465r resumes normal operation. in this manner, th e auto-restart can alternately enable and disable the switching of the power sensefet until the fault condition is eliminated (see figure 20). figure 20. auto restart operation 3.1 overload protection (olp) : overload is defined as the load current exceeding a preset level due to an unexpected event. in this situ ation, the protection circuit should be activated to protect the smps. however, even when the smps is in the normal operation, the overload protection circuit can be activated during the load a lim_spec dc p y fb lim_comp n iv n r i i ?

fscm0465r green mode fairchild power switch (fps?) ? 2006 fairchild semiconductor corporation www.fairchildsemi.com fscm0465r rev. 1.0.1 12 transition. to avoid this undesired operation, the overload protection circuit is designed to be activated after a specified time to determine whether it is a transient situation or an ov erload situation. because of the pulse-by-pulse current limit capability, the maximum peak current through the sensefet is limited and the maximum input power is restricted with a given input voltage. if the output cons umes beyond this maximum power, the output voltage (v o ) decreases below the set voltage. this reduces the current through the opto- coupler led, which also reduces the opto-coupler transistor current, increasing the feedback voltage (vfb). if vfb exceeds 2.5v, d1 is blocked and the 5.3a current source (i delay ) starts to charge c b slowly up to v cc . in this condition, vfb continues increasing until it reaches 6v, when the switching operation is terminated as shown in figure 21. the delay time for shutdown is the time required to charge c b from 2.5v to 6.0v with 5.3a (i delay ). a 10 ~ 50ms delay time is typical for most applications. figure 21. overload protection 3.2 over-voltage protection (ovp) : if the secondary- side feedback circuit were to malfunction or a solder defect causes an opening in the feedback path, the current through the opto-coupler transistor becomes almost zero. in th is case, vfb climbs up in a similar manner to the overload sit uation, forcing the preset maximum current to be supplied to the smps until the overload protection is activa ted. because more energy than required is provided to the output, the output voltage may exceed the rated voltage before the overload protection is acti vated, resulting in the breakdown of the devices in the secondary side. to prevent this situation, an over- voltage protection (ovp) circuit is employed. in general, v cc is proportional to the output voltage and the fscm0465r uses v cc instead of directly monitoring th e output voltage. if v cc exceeds 19v, an ovp circuit is acti vated, resulting in the termination of the switch ing operation. to avoid undesired activation of ovp during normal operation, v cc should be designed to be below 19v. 3.3 thermal shutdown (tsd) : the sensefet and the control ic are built in one package. this makes it easy for the control ic to detect the heat generation from the sensefet. when the temperature exceeds approximately 145c, the the rmal protection is triggered, resulting in shutdown of the fps. 4. frequency modulation : emi reduction can be accomplished by modulating the switching frequency of a switched power supply. frequency modulation can reduce emi by spreading the energy over a wider frequency range than the bandwidth measured by the emi test equipment. the amount of emi reduction is directly related to the dept h of the reference frequency. as can be seen in figure 22, the frequency changes from 63khz to 69khz in 4ms. figure 22. frequency modulation 5. soft-start : the fscm0465r has an internal soft-start circuit that increases pwm comparator inverting input voltage, together with the sensefet current, slowly after it starts up. the typical soft-start time is15ms. the pulse width to the power switching device is progressively increased to establish the correct working conditions for transformers, rectifier diodes, and capacitors. the voltage on the output capacitors is progressively increased with the intention of smoothly establishing the required output voltage. preventing transformer saturation and reducing stress on the secondary diode during startup is also helpful. v fb t 2.5v 6.0v overload protection t 12 = c b *(6.0-2.5)/i delay t 1 t 2 fscm0465r rev. 00 t s t s t s drain current f s 66khz 69khz 63khz 4ms t fscm0465r rev. 00
