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 TV and big panel backlighting applications with MPS patented pending technology.
With a 12V input VIN and a high voltage source VINH, EV4601EF-00A can deliver a regulated voltage (VINH to VINH+60V) to drive a LED string over 350V. The LED current is regulated to about 120mA. The EV4601EF-00A can be synchronized. Several EV4601EF-00As can be used together to drive a TV panel
