一款小巧的36 - 72V DC输入, 3.3V/10A输出的电源

资料介绍
摘要:紧凑型电源提供电流高达10A使用MAX5052A PWM控制器稳压3.3V这里所描述的。此电源供电来源-36V至-72V ,采用同步整流实现10A效率大于88% 。它使用了一个单晶体管正激变换器的复位绕组,有50%的最大占空比。它具有输入反向电压保护,将规范零负载。隔离电压为1500V ,并有过电压和过电流保护。它可以打开和关闭远程开/关针,它具有热关断功能,温度过高保护供应。单位有断续电流限制,以限制输出短路时的RMS电流。

A Compact 36-72V DC Input, 3.3V/10A Output Power
Supply

Abstract: A compact power supply that provides a regulated 3.3V at currents up to 10A using the MAX5052A
PWM controller is described here. This power supply operates from -36V to -72V and uses synchronous
rectification to achieve efficiencies greater than 88% at 10A. It uses a single transistor forward converter with a
reset winding and has a maximum duty cycle of 50%. It has input reverse voltage protection, and will regulate
to zero load. The isolati……
