Contributes to Lower Standby Power and Higher Efficiency
Critical Conduction Mode
PFC Controller ICs
BD769xFJ / BM1C001F
Features
●IC回路電流低減による低消費電力、高効率の実現
Low circuit current increases efficiency while reducing power consumption
●最大駆動周波数（220kHz, 400kHz, 1MHz）で軽負荷時
の効率UP
High drive frequencies (220kHz, 400kHz, 1MHz) improve efficiency
during light loads
●PFC停止機能を任意の負荷に設定出来る事で負荷の幅広い
範囲で更なる高効率を実現（BM1C001F）
The PFC stop function can be set to an arbitrary load,
enabling higher efficiency over a wide load range (BM1C001F)
Applications
