产品详细介绍

CXSD62524 CXSD62524C develops high efficiency synchronous step-down DC/DC converter capable of delivering 1A. CXSD62524 CXSD62524C operates over a wide input voltage range from 4.5V to 27V and integrate main switch and synchronous switch with very low R_DS(ON) to minimize the conduction loss.CXSD62524 CXSD62524C 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 500 kHz under heavy load conditions to minimize the size of inductor and capacitor.
