DESCRIPTION

The EV2480DN-00A Evaluation Board is

designed to demonstrate the capabilities of

MP2480DN. The MP2480 is step-down switching

regulator to deliver a constant current of up to 3A

for high power LED

With a 30-36V input VIN and a EN DC signal

which is higher than 2V, EV2480DN-00A can

deliver a regulated voltage to drive a LED string.

The LED current is regulated to about 2A.
