ETA1637
Synchronous LED Driver with 0.1% Dimming Accuracy The ETA1637 is a driver specially designed for backlighting. 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 MOSFET. It runs at an optimal 0.6MHz frequency that enables the use of small external components while still providing the best efficiencies.
