Package Pin Description
FUNCTION
Voltage ID DAC inputs. These pins are internally pulled up to 5V if left
open. VID4 selects the DAC range. When VID4 is high (logic one), the
Error Amp reference range is 2.125V to 3.525V with 100mV increments.
When VID4 is low (logic zero), the Error amp reference voltage is 1.325V
to 2.075V with 50mV increments.
Soft Start Pin. A capacitor from this pin to LGnd sets the Soft Start and
fault timing.
Off-Time Capacitor Pin. A capacitor from this pin to LGnd sets both the
normal and extended off time.
Current Sense Comparator Inverting Input
Input Power Supply Pin.
High Side Switch FET driver pin.
High Current ground for the GATE(H) and GATE(L) pins.
Low Side Synchronous FET driver pin.
Power-Good Output. Open collector output drives low when VFB is out
of regulation.
Reference ground. All control circuits are referenced to this pin.
Error Amp output. PWM Comparator reference input. A capacitor to
LGnd provides Error Amp compensation.
Error Amp, PWM Comparator feedback input, Current Sense
Comparator Non-Inverting input, and PWRGD comparator input.
