? 2016 fairchild semiconductor corporation www.fairchildsemi.com FL5150/60 ? 1.0 15 FL5150/60 igbt and mosfet ac phase cut dimmer controller description (refer to figure 1 to figure 5) present ac controls or dimmer switches typically use triac circuits to generate the ac symmetric chopped or phase cut current function . the triac is basically two back to back scr transistors that allow for symmetric ac operation in both the positive and negative half cycles . the triac dimmer circuit controls the ac voltage pulse width to the load by turning off the triac when its holding current is below the minimum threshold level . this occurs near the ac zero-crossing . the triac is turned on at a selected phase angle during the half cycle . the triac minimum holding current can become an issue for newer low wattage lighting products . in addition, newer lighting products typically have capacitive load impedance so the current and voltage phases are shifted . this can cause problems for the detection of the ac zero-cross signal and lead to unwanted flickering. the fl51 50/ 60 controller address es these issues by controlling back to back mosfet or igbt transistors which can be turned on or off at any time during the ac half cycle . in addition, the fl5160 can use the earth ground leakage current to better determine the zero- cross threshold for non-resistive loads . up to 500 a of ground leakage current is now allowed per the ul1472 2nd edition specification for 2-wire applications . the fl5160 product is for north america 120 v ac , 60 hz applications and the FL5150 product is for 230 v ac , 50 hz applications . the internal timing oscillator is selected for 50 hz for the FL5150 and 60 hz for the fl5160 . for the below description, the timing information is in reference to the fl5160 60 hz option . for the FL5150 option, the t on pulse width is scaled by +20%. the fl5160 has a selectable dim mode pin that allows for either trailing edge or leading edge dimming modulation. at startup when an under-voltage lockout en able signal is detected (por) the dim mode pin is monitored for its logic state and after 60ms this state will be latched and program the fl5160 for either trailing edge dimming if this pin is low or leading edge dimming if this pin is high . the dim mode pin enables a 10 a pull up current source after power- on -reset (por) . once the dimming mode is latched, this pin will be di sabled until a por enable signal occurs . for trailing edge dimming, the gate pulse is enabled at the zc signal and disabled after the t on pulse width per table 5 . for leading edge dimming, the gate pulse is disabled at the zc signal and enabled after the t off pulse width per table 5. the gate pulse width is determined by the value of the voltage at the dim control pin . the dim control pin sources a 10 a current . the voltage at this pin is connected to an 8 bit adc with an internal full scale reference of 2.56 v so the adc step size is ~ 10 mv . table 5 shows the gate pulse width versus the dim control pin voltage for a 60 hz fl5160 application . if the dim control pin is connected to vdd a force 100% duty cycle will be selected . however, if the vs voltage drops to the por voltage threshold a logic reset will occur . a 100% duty cycle can only be selected for a 3- wire application (neutral wire present). when the voltage on the dim control pin is changed, the fl5160 will increase or decrease the dim steps by one step every 4.17 ms (or two steps per half cycle) . this provides for a smooth dim pulse width transition . from minimum to maximum pulse width, the fl5160 will control the dim ramp rate to about 1 second. the fl5160 has an internal difference amplifier which measures the voltage difference across q1 and q2 . with the external oc sense 1&2 resistors, this diff amp will measure the voltage difference across the collectors or drains of q1 and q2 when the drv gate signal is high . if the maximum voltage threshold is exceeded for longer than 50 ? s the gate pulse will be disabled until the next ac zero-crossing . this feature will limit the maximum load current and also limit the power dissipation for q1 and q2 . if 16 consecutive over current pulses occur ( see figure 12 ) the fl5160 will disable the drv gate and require a por to reset the disable state . the oc (over-current) trip threshold is dynamic: it is a function of the v ac phase angle . the oc threshold is higher at startup to allow for higher transient currents during start up typical of incandescent bulbs. the desired steady state (phase angle> 90) over- current threshold can be programmed with the following equation: | q1 vd C q2 vd | = 2 x r sense i oc x r dson + v f = 2 x r sense (1) where: r dson = mosfet drain to source resistance v f = mosfet body diode so, i oc = (2 x r sense C vf) / r dson note: r sense in m ? (2) for the fdpf33n25 transistor, r dson = 94 m ? and v f = 0.7 v @25c r dson = 170 m ? and v f = 0.6 v @100c (3) so, i oc = 13.8 a @25c with r sense = 1 m ? i oc = 8.2 a @100c with r sense = 1 m ? (4) the fl5160 has a low power electronic off state feature. if an external npn transistor is connected per figure 2 , the power consumption for the off state can be significantly reduced. when an off state is selected (dim control pin at 0 v) an internal 100 ms timer starts. after the timer expires, the fan5160 will enable an internal pmos transistor which shorts the low power and vs pins. this will turn off q3 which de-biases r1. the fl5160 is now biased by r2. this reduces the electronic off state power consumption from 1 w to 100 mw for a 120 v ac inpu t.
? 2016 fairchild semiconductor corporation www.fairchildsemi.com FL5150/60 ? 1.0 16 FL5150/60 igbt and mosfet ac phase cut dimmer controller figure 4 shows a typical 3 wire application . for a three wire application, the neutral wire is available in addition to the line hot and load hot connections . external components d1, r1 and c2 pr ovide for the dc bias of the fl516 0. during the ac half cycle when line neutral is positive, the c2 capacitor will charge positive and be clamped to 17 v by the fl516 0s shunt regulator connected to vs. the gate driver circuit is supplied from the vs pin. during the ac half cycle when line neutral is negative, the fl5160 is biased by the capacitor c2. figure 8 shows the vs, drv gate and load current waveforms for a led load. the pulse width can be controlled from 0 to 100% duty cycle with a 3-wire application. the r zc monitor resistor detects the ac zero crossing. the typical value for this resistor is 1 m ? for 1 20 v ac applications. figure 1 shows a typical 120 v ac 2-wire application. this 2-wire application does not have the neutral wire available, which is typical for most switch box applications in north america: only the line hot, load ho t and earth ground wires are available. the fl5160 is powered from the ac line by d1, d2, r1 and c2. capacitor c2 charges when the q1 & q2 transistors are off. when q1 and q2 are on, c2 provides the bias for the fan5160. since c2 can only charge when both q1 and q2 are off, a 100% duty cycle is not possible. the maximum duty cycle is determined by the load; however, because the fl5160 has a low quiescent current, an output voltage typically >95% of the ac line voltage is possible. figure 9 shows the vs, drv gate and load current waveforms for a led load. for the r1 and c2 values shown, a maximum gate pulse of 6.5 ms is possible. however, some led loads will not allow a 6.5 ms maximum gate pulse. th e fl5160 has a dim control override feature for led loads that do not support a maximum gate pulse of 6.5 ms (auto m ax .). the fl5160 detects when the maximum gate pulse width occurs and overrides the dim control voltage to provide the maximum load voltage without flicker. this feature automatically adjusts per the load impedance . the power dissipation for r1 (figure 1) is highest when an off state is selected. to reduce the power dissipation for r1, an emitter follower current mirror circuit can be used as shown per figure 3 . zener z1 (7.5 v) will bias r1 so ~3.5 ma flows through r1, independent of the vac voltage. the power dissipation for r1 will be ~25 mw. the power dissipation for q3 will be ~425 mw. the above description refers predominantly to the fl5160 functionality. the FL5150 controller is the same as the fl5160 except the internal timer is trimmed for a 50 hz ac frequency. whereas the above applications refer to v ac input voltages of 120 and 230, other ac voltages can be used as long as the discrete components are correctly scaled.
