产品概述 返回TOP
The CXSD62341 develops a high efficiency synchronous step-down DC-DC converter capable of delivering 3A
load current. The CXSD62341 operates over a wide input voltage range from 4.5V to 40V and integrates main
switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.The CXSD62341 adopts peak current control scheme. The switching frequency is adjustable from 500kHz to 2.5MHz using an external resistor. The device also features ultra low quiescent operating to achieve high efficiency under light load. And the internal soft-start limits inrush current during power on. CXSD62341 is available in TSOT23-8 package.
