   产品概述 返回TOP6ho嘉泰姆


    CXSD62371 is a 6A, 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 CXSD62371 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 GCXSD62371is intended for the power supply of Notebook Computer, or other low-voltage supplies as low as 0.75V. The GCXSD62371is available in QFN3X3-24 package.
