产品概述 返回TOPzXK嘉泰姆

The CXSD62540 develops a high efficiency synchronous step down DC/DC converter capable of delivering3Aload current. The CXSD62540 operates over a wide input voltage range from 4.5V to 40V and integrates main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss.The CXSD62540 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.CXSD62540 is available in TSOT23-8 package.
