ETA1638
ETA1638 Synchronous LED Driver with 0.1% Dimming Accuracy in DFN2x2 The ETA1638 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 with an optimal 0.6MHz frequency that enables the use of small external components while still providing best efficiencies.
