　　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.
