High Efficiency 10A Synchronous Buck Converter

General Description

G5335 is a 10A, synchronous DC/DC buck converter with integrated 20mΩ N-channel high-side MOSFETand 8.5mΩ N-channel low-side MOSFET. It uses con-stant on-time control scheme to handle wide in-put/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while main-taining a relatively constant switching frequency. The G5335 achieves high efficiency at a reduced cost by eliminating the current-sense resistor found in tradi-tional current-mode PWMs. Single-stage buck conver-sion allows these devices to directly step down high-voltage batteries for the highest possible effi-ciency. The G5335 is intended for the power supply of Notebook Computer, or other low-voltage supplies as low as 0.8V. The G5335 is available in QFN4X4-23 package.
