LT3755-1 - LED Controller

Download the LT3755-1 datasheet PDF. This datasheet also covers the LT3755 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®3755, LT3755-1 and LT3755-2 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.
