ETA1627 Description
The ETA1627 is a driver specially designed for back-lighting. It consists of a high accuracy current sink that allows low duty dimming and a high efficiency step-up converter with an integrated 40V power MOSEFT. It runs with an optimal 0.8MHz frequency that enables use of small external ponents while still providing best efficiencies.
