ETA1638規(guī)格書詳情
描述 Description
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 external components while still providing best efficiencies.
