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% VIN)
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.
