产品概述 返回TOP1H5嘉泰姆

       CXSD62546 develops a high efficiency synchronous step down DC/DC converter capable of delivering 5A output current. CXSD62546 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.CXSD62546 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.
