BD94122F - White LED Driver
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 s
BD94122F 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 S
