FSL5x8A/H 是一款集成峰值电流模式控制脉冲宽度调制 (PWM) 电源开关，专为离线开关模式电源而设计。PWM 控制器包括高级软启动、跳频、优化的栅极驱​​动器、内部跨导放大器、用于环路补偿的温度补偿精密电流源以及增强的自我保护电路。与分立式 MOSFET 和 PWM 控制器解决方案相比，FSL5x8A/H 可以降低总成本、减少元件数量、减小尺寸和减轻重量，同时提高效率、生产率和系统可靠性。该设备为经济高效地设计隔离式和非隔离式反激式转换器提供了一个基本平台。

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.
