Thermally enhanced

Low V_FBStep-Down LED Driver

ADT6780

General Description

The ADT6780 is a thermally enhanced current mode step down LED driver. That is designed

to deliver constant current to high power LEDs. The device is suitable for various high power

LED application due to the wide operating range(VIN 4.5V~28V) and high output

capability(continuous 2A). with a very low feedback voltage(V_FB=0.2V) power dissipation can

be minimized. Fault condition protection includes cycle-by-cycle current limiting and thermal

shutdown.

The package is available in a standard SOP8-PP(with Exposed pad) package.
