BD94122F中文资料PFC Direct Current Resonance Type White LED Driver for Large LCD数据手册ROHM规格书
BD94122F规格书详情
描述 Description
BD94122F is a current resonance type LED Driver, which can connect to PFC directly. LED current is controlled by driving output frequency. Because this IC can use half bridge structure, it can reduce the number of external components. BD94122F has some protection functions against fault conditions such as Over Voltage Protection(OVP), LED Short Protection(LSP) and LED Open Protection Detection(LOP).
特性 Features
• 1 Channel Push Pull Control
• Current Feedback by Driving Frequency Resolution
• Timer Latch Circuit
• Under Voltage Detection for IC’s Power Line (VCC UVLO)
• Output Over Voltage Protection
• Driving Output Frequency (Minimum Frequency Setting) Tolerance: ±5%
• Error Signal Output from FAIL Pin
• Control IC Power On and Off by STB Pin
• Burst Control by External PWM
• Analog Dimming by External DC
• Pulse/DC Conversion Function for ADIM
