9 / 36 page LTC3860 9 3860fc FUNCTIONAL DIAGRAM PIN FUNCTIONS A change in VIN immediately modulates the input to the PWM comparator and changes the pulse width in an in- versely proportional manner, thus bypassing the feedback loop and providing excellent transient line regulation. An external lowpass filter can be added to this pin to prevent noisy signals from affecting the loop gain. TRACK/SS1 (Pin 32), TRACK/SS2 (Pin 9): Soft-Start. The voltage ramp rate at these pins sets the voltage ramp rate of the outputs. Self soft-start is accomplished by placing a capacitor to ground. 22 ISNS1P 21 ISNS1N 20 23 18 28 ISNS2N IAVG ILIM2 ILIM1 20μA 21μA 20μA 10 FREQ 13 PHSMD 12 CLKOUT 11 16 CLKIN 3860 BD OC1 NOC1 OC2 NOC2 19 ISNS2P x18.5 x18.5 8 FB2 7 COMP2 9 TRACK/SS2 EA2 REF REF 2 FB1 32 TRACK/SS1 3 COMP1 EA1 + + – + + – + – + – 5 VSNSN 24 RUN1 100k VCC 1.5μA 1.5μA VCC 17 RUN2 6 VSNSP 4 VSNSOUT DA S VFB1 ILIM1 VFB2 ILIM2 S MASTER/SLAVE/ INDEPENDENT?
