VIDO – VID4
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 incre-
ments. When VID4 is low (logic zero), the Error amp reference voltage
is 1.325V to 2.075V with 50mV increments.

VCC1
Input power supply pin for the internal circuitry, and low side gate
driver. Decouple with filter capacitor to PGnd.
17
GATE(H)
High side switch FET driver pin for VCORE section.
18
PGnd
Power ground for VCORE and VI/O section.
19
GATE(L)
Low side synchronous FET driver pin.
16
VCC2
Input power supply pin for on-board high side gate drivers. Decouple
with filter capacitor to PGnd.
15
GATE
High side switch FET driver pin for VI/O section.
21
OVP
Overvoltage protection pin. Goes high when overvoltage condition is
detected on VFB1.
22
PWRGD
Power-Good Output. Open collector output drives low when VFB1 is
out of regulation.
