0.75V至3.6V可调输出60μA的低静态电流CXSD62373A可编程开关频率3V至28V适配器或电池输入负载阶跃响应的准脉宽调制

The CXSD62373 CXSD62373A is intended for the power supply of Notebook Computer, or other low-voltage supplies as low as 0.75V. The CXSD62373 CXSD62373A is available in QFN4X4-28 package.CXSD62373 CXSD62373A is a 10A, synchronous DC/DC buck converter with integrated 20mΩ N-channel high-side MOSFET and 8.5mΩ 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 CXSD62373 CXSD62373A 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.
