LT3796 - Constant-Voltage Controller

General Description

The LT®3796/LT3796-1 are DC/DC controllers designed to regulate a constant-current or constant-voltage and are ideal for driving LEDs.

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