ETA1638 Datasheet (ETA) - Synchronous LED Driver

ETA1638, Synchronous LED Driver

The ETA1638 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 low side and high side power MOSEFT.

It runs with an optimal 0.6MHz frequency that enables use of small ex

ETA1638 Features

* of ETA1638 is that it provides an accurate current at dimming duty cycle down to 0.1%. This is very important for backlights that need to dim to very low light while still providing good consistency. For maximum protection, the ETA1638 has an internal OVP protection at 30V to prevent the chip from d
