PIN SYMBOL  
IDO – VID4  
FUNCTION  
V
Voltage ID DAC inputs. These pins are internally pulled up to  
5.65V 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.

12  
Low side synchronous FET driver pin.  
Power-Good Output. Open collector output drives low when  
VFB is out of regulation.  
13

COFF  
Off-Time Capacitor Pin. A capacitor from this pin to Gnd sets  
the off time for the regulator  
Error amp output. PWM comparator inverting input.  
A capacitor on this pin provides error amp compensation.
