LT3756-1 - LED Controller

Download the LT3756-1 datasheet PDF. This datasheet also covers the LT3756 variant, as both devices belong to the same led controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LT®3756, LT3756-1 and LT3756-2 are DC/DC controllers designed to operate as a constant-current source for driving high current LEDs.

They drive a low side external N-channel power MOSFET from an internal regulated 7.15V supply.
