Description

The EV4601EF-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP4601EF for TV backlighting applications. MP4601 is an integrated Buck- Boost white LED driver which is suitable for TVand big panel backlighting applications with MPS patented pending technology.With a 12V input VIN and a high voltage sourceVINH, EV4601EF-00A can deliver a regulatedvoltage (VINH to VINH+60V) to drive a LED stringover 350V. The LED current is regulated toabout 120mA. The EV4601EF-00A can besynchronized. Several EV4601EF-00As can beused together to drive a TV panel
