General Description
G5329 is a 8A, synchronous DC/DC buck converter
with integrated 30mΩ N-channel high-side MOSFET
and 15mΩ 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
G5329 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 G5329 is intended for the main power
supply for the networking system or other low-voltage
supplies as low as 0.8V. The G5329 is available in
QFN4X4-32 package.
