Fairchild FSL336LR最高效率开关电源解决方案

Fairchild公司的FSL336LR是650 V Green Mode降压开关,具有最高的电源效率和系统设计灵活性.器件集成了PWM和SenseFET,高压电源稳压器以及跨导放大器,降低外接元件和不需要辅助偏压线圈,固定工作频率50kHz,具有多种保护如过流保护(OLP),过压保护(OVP),反馈开路保护(FB­_OLP)和热关断(TSD),主要用在多种设备的开关电源.本文介绍了FSL336LR主要特性,框图,7W参考设计主要指标, 变压器主要指标,电路图,材料清单和PCB元件布局图.

The FSL336LR integrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for high-performance offline buck, buck-boost, and non-isolation flyback Switched Mode Power Supplies (SMPS) with minimal external components. This device integrates a high-voltage power regulator that enables operation without auxiliary bias winding. An internal transconductance amplifier reduces external components for the feedback compensation circuit.
