Description

1COMP

Error amplifier output. Connects to the compensation network.

Chip enable pin. Active HIGH. Connects to a power source through a 10K to100K resistor to enable.

BOOT

Connect to 0.1 µF capacitor from VSW to BOOT to power the high side gate driver.

4VSW

Inductor Connection. Connect an output filter inductor to this pin. VSW is high impedance when the IC is

in shutdown mode.

GND

GROUND pin.

6VIN

Supply voltage.

7VREG

Internal regulator output. An external 4.7 µF decoupling capacitor is required at this pin.

Output voltage feedback input.
