   产品概述 返回TOPtkF嘉泰姆

The device adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads. In addition, it operates at pseudo-constant frequency of 500kHz under continuous conduction mode to minimize the size of inductor and capacitor.The CXSD62553 develops a high efficiency synchronous step-down DC/DC regulator capable of delivering 16A current. The device integrates main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss. The CXSD62553 operate over a wide input voltage range from 4V to 18V.
