PIN DESCRIPTION (continued)
Pin Name Description Applications Information
13 CS2 Current Sense Input, Controller 2 Input for current mode control and the current limit sensing. If the CS2 pin
exceeds 0.5V the OUT2 pulse is terminated producing cycle-by-cycle current
limiting. External resistance connected to CS2 will adjust (increase) PWM slope
compensation. This pin's voltage must not exceed 1.25V.
14 COMP2 PWM Control, Controller 2 The COMP2 input provides voltage feedback to the PWM comparator inverting
input of Controller 2 through a 3:1 divider. The OUT2 duty cycle increases as
the COMP2 voltage increases. An internal 5kΩ pull-up resistor to +5.0V
provides bias current to the opto-coupler transistor.
15 DCL Duty Cycle Limit An external resistor sets the maximum allowed duty cycle at OUT1 and OUT2.
16 RT/SYNC Oscillator Adjust and Synchronizing An external resistor sets the oscillator frequency. This pin also accepts ac-
input coupled synchronization pulses from an external source.
