DESCRIPTION

NO.

NAME

VCC

Driver supply voltage pin: output of internal regulator powering low side NMOS driver. A minimum of

0.47 µF must be connected from this pin to PGND for proper operation.

Low-side NMOS gate driver output: output gate drive to low side NMOS gate.

PGND

Power ground: ground for power section. External power circuit reference. Must be connected to

AGND at a single point.

High side NMOS gate driver output: output gate drive to high side NMOS gate.

EN/MODE

Multi-function input pin: this input provides for chip enable, and mode selection. See Device

Functional Modes for details.

Feed-back input pin: negative input to error amplifier. Connect to feedback resistor tap to regulate

output.

COMP

Compensation pin: a resistor and capacitor combination connected to this pin provides frequency

compensation for the regulator control loop.

AGND

Analog ground: ground for analog control circuitry. Reference point for all stated voltages.

ISEN

Current sense input: current sense input, with respect to VIN, for all current limit functions.

VIN

Power supply input pin: input supply to regulator. See Application and Implementation for

recommendations on bypass capacitors on this pin.
