G5330AQN1U

G5330A is a 10A, synchronous DC/DC buck converter with integrated 20m N-channel high-side MOSFET and 8.5m 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 G5330A 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 80mA for internal circuit with automatic bootstrapping to DC/DC converter output. The G5330A is intended for the 5V system power supply of Notebook Computer. The G5330A is available in QFN4X4-28 package.
