DK5V100R25S Overview

启动 芯片内置储能电容和自供电线路,可以实现芯片和功率 MOS 管驱动需求,无需外接电源。当 K 极电压高于 A 极时,通过自供电线路,给 Vcc 供电,Vcc 电压逐渐上升。在 Vcc 电压低于启动电压 Vcc_on 时,内置功率 MOS 管关闭,当 Vcc 电压大于 Vcc_on 时,结束启动状态。当 Vcc 电压降低到 复位电压 Vcc_off 以下时,芯片重新进入启动状态。 2. NMOS 控制 当检测到 A、K 端正向导通电压大于开通电压 VON 时,则打开 NMOS 管;芯片实时检测 K 点电 压变化,依据 K 点电压变化,判断系统工作模式。在 CCM 模式时,通过智能算法算出当前周期 NMOS 管开通时间 TON,当 NMOS 管开通时间达到 TON,关闭 NMOS 管。在非 CCM 模式时,当检测到流 过功率 MOS 管的电流逐渐减小到 0 时,则关闭功率 MOS 管。 3. RC 吸收电路...
