Pin Descriptions

Pin Number

Name

Description

A1

Mode

Auto mode and forced PWM mode selection. Forced PWM = HIGH; Auto = LOW.

A2

VIN

Power supply input. Connect to the input filter capacitor (Typical Application Circuit, page 1).

B1

SW

Switching node connection to the internal PFET switch and NFET synchronous rectifier.

B2

EN

Enable pin. The device is in shutdown mode when voltage to this pin is < 0.4V and enabled

when > 1.2V. Do not leave this pin floating.

C1

FB

Feedback analog input. Connect directly to the output filter capacitor (Typical Application

Circuit, page 1).

C2

GND

Ground pin.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

Junction-to-ambient thermal resistance is highly application and board-layout dependent. In applications where high power dissipation

exists, special care must be given to thermal dissipation issues in board design.
