ADT6752 Datasheet, PDF (1/1 Pages) ADTech – Step-down converter designed for driving high power LEDs

ADT6752
General Description
The ADT6752 is a step-down converter designed
for driving high power LEDs. It operates wide
input supply voltage range from 6V to 60V with
1A continuous output current. By using current
mode control, it has excellent 1.5% output current
accuracy and 96% high efficiency.
With enhanced protection functions, ADT6752
operates safely against abnormal circumstance.
The ADT6752 is available in small outline SOP8-
PP(with Exposed pad) package.
