   产品概述 返回TOPuip嘉泰姆

     CXSD62357 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 CXSD62357 achieves high efficiency at a reduced cost by eliminating the current-sense resistor found in traditional current-mode PWMs. Efficiency is further enhanced by an ability to drive very large synchronous rectifier MOSFETs. Single-stage buck conversion allows these devices to directly step down high-voltage batteries for the highest possible efficiency. The noiseless pulse-skipping mode setting maintains the switching frequency above 25kHz to eliminates the audio noise. The CXSD62357 is intended for CPU core, chipset, DRAM, or other low-voltage supplies as low as 0.5V. The CXSD62357 is available in TQFN2X2-12 package.
