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. 5 SS Soft Start Pin. A capacitor from this pin to LGnd sets the Soft Start and fault timing. 7COFF Off-Time Capacitor Pin. A capacitor from this pin to LGnd sets both the normal and extended off time. 8ISENSE Current Sense Comparator Inverting Input 9VCC Input Power Supply Pin. 10 GATE(H) High Side Switch FET driver pin. 11 PGnd High Current ground for the GATE(H) and GATE(L) pins. 12 GATE(L) Low Side Synchronous FET driver pin. 13 PWRGD Power-Good Output. Open collector output drives low when VFB is out of regulation. 14 LGnd Reference ground. All control circuits are referenced to this pin. 15 COMP Error Amp output. PWM Comparator reference input. A capacitor to LGnd provides Error Amp compensation. 16 VFB Error Amp, PWM Comparator feedback input, Current Sense Comparator Non-Inverting input, and PWRGD comparator input.
