内带监控器的高电压电流型PWM控制器HV9606应用

Application of High Voltage Current Mode PWM Controller HV9606 With Supervisor

本文介绍一款高电压电流型PWM控制器HV9606。该芯片功能齐全,专用内部监控器有效的减小了输出电容容量,超低工作电流,软启动时间可调,电源电压V_(DD)最低可降至2.9V,适用于同步正激、正激和反激单端变换器控制器,并给出了具体应用电路。

A current-mode PWM controller with supervisor HV9606 introduced in this paper witch reduces output capacitance up to 40%. Ultra-low operation current, operation voltage down to 2. 9V, and soft start programmable. HV9606 widely used in design synchronous forward, forward, and flyback controller.
