FSL538中文资料High Performance 800 V Off-line Switcher with HV Startup and SenseFET数据手册ONSEMI规格书

描述 Description

The FSL5x8A/H is an integrated peak-current-mode controlled pulse width modulation (PWM) power switch, specifically designed for off-line switch-mode power supplies. The PWM controller includes an advanced soft-start, frequency hopping, optimized gate driver, internal transconductance amplifier, temperature-compensated precise current source for loop compensation and enhanced self-protections circuitry as well. Compared with a discrete MOSFET and PWM controller solution, the FSL5x8A/H allows to reduce total cost, component count, size, and weight, while simultaneously increase efficiency, productivity, and system reliability. This device provides a basic platform for cost-effective design of both isolated and non-isolated Flyback converters.

简介

FSL538属于集成电路（IC）的ACDC转换器离线开关。由制造生产的FSL538AC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
