【产品】国产集成500V高压MOSFET的PWM控制功率开关KP35026，空载待机功耗低于20mW

时间： 2022-06-19 来源：必易微

技术问答

必易微推出的KP35026是一款高性能低成本PWM控制功率开关，适用于3.3V供电的应用场合，外围电路简单、器件个数少。同时IC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，产品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。芯片采用了多模式PWM控制技术和动态响应优化电路，有效提升了动态响应能力，优化了线性调整率和负载调整率，同时明显降低了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。且产品集成有完备的带自恢复功能的保护功能：VDD欠压保护、输出过压保护、逐周期电流限制、异常过流保护、过热保护和过载保护等。

主要特点

• 固定输出3.3V

• 快速动态响应，满足WIFI供电要求

• 空载待机功耗低于 20mW

• 集成续流二极管
