产品简介

CXSD62536开发了一种能够输出3A输出电流的高效同步降压DC/DC变换器。在4.5V到23V的宽输入电压范围内工作，集成了主开关和同步开关以及极低的RDS（ON），以最大限度地降低传导损耗.采用瞬时脉宽调制结构，可在高降压应用中实现快速瞬态响应，并在轻负载下实现高效率。此外，它在连续导通模式下以500kHz的伪恒定频率工作，以减小电感和电容的尺寸

   产品概述 返回TOP

 

        CXSD62536 develops a high efficiency synchronous step down DC/DC converter capable of delivering 3A output current. CXSD62536 operates over a wide input voltage range from 4.5V to 23V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

CXSD62536 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.
