G5329AQV1U     QFN4X4-32

General Description

G5329A is a 12A, synchronous DC/DC buck converter

with integrated 20mΩ N-channel high-side MOSFET

and 8.5mΩ N-channel low-side MOSFET. It uses constant

on-time control scheme to handle wide input/

output voltage ratios with ease and provides 100ns

“instant-on” response to load transients while maintaining

a relatively constant switching frequency. The

G5329A achieves high efficiency at a reduced cost by

eliminating the current-sense resistor found in traditional

current-mode PWMs. Single-stage buck conversion

allows these devices to directly step down

high-voltage batteries for the highest possible efficiency.

The built-in 5V LDO supports 10mA for internal

circuit. The G5329A is intended for the main power

supply for the networking system or other low-voltage

supplies as low as 0.8V. The G5329A is available in

QFN4X4-32 package.
