欧创芯 基于 OC580X 设计的降压恒压恒流应用 应用及方案
芯片是一款支持宽输入电压的开关降压型 DC-DC 驱动器,最高支持 150V 输入;
芯片输出电压可做到 4.2V-30V 输出范围;
芯片驱动能力强,外置 MOS 可驱动 10A 输出;
芯片的待机功耗低,最低待机功耗在 700uA 以内;
芯片采用固定工作频率 140KHZ,并且在轻负载下降低工作频率,提高轻载下的整机工作效率;
芯片同时支持恒压和恒流输出,恒流输出可通过 CS 电阻设置恒流值,恒压通过FB1,FB2 分压电阻设置输出电压值;
芯片内部集成 VDD 稳压钳位管,低输入电压应用 30V 以内外部可不接稳压管;
芯片具有优异的母线电压调整率和负载调整率;
芯片集成过温保护,软启动,输出短路保护,输出过流保护,输出过载保护,提高工作稳定可靠性。
