Global Mixed-mode Technology

Asynchronous Voltage Mode Controller

Features

General Description

The G5320 is a flexible asynchronous buck controller

Input Voltage: 4.5V to 27V

Output Voltage (700mV to 90% V_IN)

with a built in 200mA driver for P-channel FETs. The

input voltage is up to 27V. The G5320 operates with

voltage-mode feedback and has feed-forward in-

put-voltage compensation that responds instantly to

input voltage change. The internal 700mV reference is

trimmed to 1%, giving accurate output voltages. Clock

frequency, soft-start, and overcurrent limit are each

easily programmed by a single, external component.

Over voltage protection (OVP) can be adjusted by set-

ting the external resistors. Input under-voltage lockout

is implemented. The G5320 is available in 10-pin

MSOP exposed pad package.
