Buck LED Driver

Buck LED Driver for Automotive

Suitable for Matrix LED Control

BD18395EFV-M

General Description

Key Specifications

BD18395EFV-M is a Buck LED driver suitable for matrix

LED control. It has a wide input voltage range from 4.5 V

to 70 V with a possible average output current of 2.0 A

max. A shutdown function reduces power consumption.

The LED current can be set by an external current setting

resistor, and it operates by peak current detection OFF

TIME control. The device includes self-protection

features such as UVLO, overcurrent protection, LED

open detection, low output voltage detection, status good

output and a thermal shutdown function.
