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.
