UCC28610 25-90W Cascoded Flyback Power Supply Controller

描述

UCC28610将交流和直流消费类电源解决方案的性能和可靠性水平提高到全新的水平。

一个脉宽调制（PWM）调制算法在整个运行范围内保持断续或转换模式运行的同时，变化开关频率和初级电流。与一个共源架构组合在一起，这些技术创新在一个传统反激式架构中改进了效率，可靠性和系统成本。

UCC28610提供一个可预期的最大功率阈值，以及一个针对过载的定时响应，从而实现对浪涌功率要求的安全处理。对于重试或锁存模式，过载故障响应是可由用户设定的。额外保护功能包括输出过压检测，可编程最大导通时间和热关断。
