BD93941EFV - ROHM

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 protection (OVP), the over current limit protection of DCDC (OC.

Features

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