DESCRIPTION

The LT®3795 is a DC/DC controller designed to regulate a

constant-current or constant-voltage and is ideal for driv

ing 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.

Spread spectrum frequency modulation (SSFM) can be

activatedforimprovedelectromagneticcompatibility (EMC)

performance. Thegroundreferredvoltage FBpinserves as

the input for several LED protection features, and also al

lows the convertertooperate as a constant-voltage source.

The maximum output current is set by an external resistor,

and the output current amplifier has a rail-to-rail common

mode range. The LT3795 also includes a separate input

current sensing amplifier that is used to limit input current.

The TG pin inverts and level shifts the PWM signal to drive

the gate of the external PMOS. The PWM input provides

LED dimming ratios of up to 3000:1, and the CTRL inputs

provide additional analog dimming capability.
