Available in 28-Lead TSSOP Package The LT®3795 is a DC/DC controller designed to regulate a
constant-current or constant-voltage and is ideal for driving LEDs. It drives a low side external N-channel power
MOSFET from an internal regulated 7.7V supply. The fixed
frequency and current mode architecture result in stable
operation over a wide range of supply and output voltages. …
