    		Kiwi Instruments 高性能、低成本离线式 PWM 控制功率开关 KP321XB 系列是一款高性能低成本 PWM 控制功率开关，适用于离线式小功率降压型应用场合，外围电路简单、器件个数少。同时产品内置高耐压MOSFET 可提高系统浪涌耐受能力。 与传统的 PWM 控制器不同，KP321XB 内部无固定时钟驱动 MOSFET，系统开关频率随负载变化可实现自动调节。同时芯片采用了多模式 PWM 控制技术，有效简化了外围电路设计，提升线性调整率和负载调整率并消除系统工作中的可闻噪音。此外，芯片内部峰值电流检测阈值可跟随实际负载情况自动调节，可以有效降低空载情况下的待机功耗。 KP321XB 集成有完备的带自恢复功能的保护功能： VDD 欠压保护、逐周期电流限制、输出过压保护、过热保护、过载保护和 VDD 过压保护等。 Original PDF
