产品概述 返回TOPvB6嘉泰姆

     CXSD62543 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 4A output current. CXSD62543 operates over a wide input voltage range from 4.5V to 30V and integrates main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss.CXSD62543 adopts the proprietary 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 continous conduction mode to minimize the size of inductor and capacitor.
