BD93941EFV Datasheet (ROHM) - White LED Driver

BD93941EFV, White LED Driver

BD93941EFV and BD93941FP is a high efficiency driver for white LEDs and designed for large LCDs.

These ICs are built-in a boost DCDC converters that employ an array of LEDs as the light source.

BD93941EFV and BD93941FP have some protect function against fault conditions, such as the over-voltage pro

BD93941EFV Features

* 4ch LED constant current driver and DC/DC converter
