TI UCC28610新型65W AC-DC电源解决方案
TI 公司的UCC28610是新型12W到65W的 AC/DC电源解决方案,它的PWM算法可随开关频率和初级电流而变化,整个工作范围内保持不连续或瞬变模式,和级联架构一起,比通常的反激架构有更高的效率,可靠性和降低系统成本,主要应用在12W到65W的 AC/DC适配器,离线电池充电器,消毒类电子产品(DVD播放器,STB,DTV,游戏机.打印机等).本文介绍了UCC28610主要特性, 简化方框图, 推荐的工作应用电路和典型设计电路.
The UCC28610 brings a new level of performance and reliability to the AC/DC consumer power supply solution.
A PWM modulation algorithm varies both the switching frequency and primary current while maintaining discontinuous or transition mode operation over the entire operating range. Combined with a cascoded architecture, these innovations result in efficiency, reliability, and system cost improvements over a conventional flyback architecture.
The UCC28610 offers a predictable maximum power threshold and a timed response to an overload, allowing safe handling of surge power requirements. Overload fault response is user-programmed for retry or latch-off mode. Additional protection features include output overvoltage detection, programmable maximum on-time, and thermal shutdown.
