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.
