OC5801L宽输入电压降压型恒压恒流DC-DC控制器
●OC5801L是一款支持宽电压输入的开关降压型DC-DC控制器,最高输入电压可超过150V。OC5801L具有低待机功耗、高效率、低纹波、优异的母线电压调整率和负载调整率等特性。支持大电流输出,输出电流可高达10A以上。
●OC5801L同时支持输出恒压和输出恒流功能。通过设置CS电阻可设置输出恒流值。通过设置FB1、FB2引脚的分压电阻可设置输出恒压值。
●OC5801L采用固定频率的PWM控制方式,典型开关频率为140KHz。轻载时会自动降低开关频率以获得高的转换效率。
●OC5801L内部集成软启动以及过温保护电路,输出短路保护,限流保护等功能,提高系统可靠性。
●OC5801L采用SOP8封装。
