Applications

„ Notebook Computers „ I/O Supply „ Chipset/RAM Supply as Low as 0.75V „ Networking Power Supply General Description G5382 is a 6A, synchronous DC/DC buck converter with integrated 30m Ω N-channel high-side MOSFET and 15mΩ 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 G5382 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 G5382 is intended for the power supply of Notebook Computer, or other low-voltage supplies as low as 0.75V. The G5382 is available in QFN3X3-24 package.
