PFC直連電流共振型大屏幕用白色LED驅(qū)動器

BD94121F是PFC直接連接的電流共振型LED驅(qū)動器。LED電流通過頻率控制。應(yīng)用可直接連接PFC，可使用半橋結(jié)構(gòu)。因此可減少外接部件的數(shù)量。BD94121F中內(nèi)置了應(yīng)對異常狀態(tài)的幾種保護功能。過電壓保護(OVP：over voltage protection), LED短路檢測(IS High檢測), LED開路檢測(IS Low檢測)等。 ? 20V High Rating Process\n? 1 Channel Push-pull Control\n?
