UD05104G-AF5-R 高频1A降压转换器

技术规格

详细描述

UD05104 是一款采用恒定频率、电流模式架构的 1A 高频同步降压 DC/DC 转换器。它专为与小型电感器和电容器一起使用而设计，占用的 PCB 面积非常小。它包括片上电源开关和同步整流器，无需外部肖特基二极管即可实现高效率。

为了最大限度地提高轻负载效率，UD05104 仅消耗 30μA 的静态电流，而在停机时消耗的静态电流小于 1μA。输出电压可调节至低至 0.6V，并且该器件具有短路和过热保护。

The UD05104 is a 1A high frequency synchronous step down DC/DC converter using constant frequency, current mode architecture. It's designed for use with small inductor and capacitor and uses very little pcb area. It includes on chip power switch and synchronous rectifier for high efficiency without an external schottky diode.

To maximize light load efficiency the UD05104 draws only 30μA quiescent current, and in shutdown it draws less than 1μA. The output voltage can be regulated as low as 0.6V and the device if protected from shorts and over temperature.
