The EV4603-S-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP4603ES for TV backlighting applications. MP4603 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, EV4603-S-00A can deliver a regulated voltage (VINH to VINH+63V) to drive a LED string over 350V. The LED current is regulated to about 120mA. The EV4603-S-00A can be synchronized. Several EV4603-S-00As can be used together to drive a TV panel.
