LT3756-2 Datasheet Led Controller

Manufacturer: Analog Devices

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

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.

The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages.
