DESCRIPTION

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

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
