DESCRIPTION

The EV4013-S-00A is designed to demonstrate

the capabilities of MPS’ MP4013 for LED

backlighting applications. The MP4013 is a

current mode controller designed for driving the

high brightness Light Emitting Diodes (LEDs)

with wide input voltage 8V-26V. It can be used

in

Boost,

Buck,

Buck-boost

and

SEPIC

topologies

With a 36-60V input PVIN and an 8-26V power

supply for MP4013, The evaluation board can

drive a single LED string with the LED current

regulated to 240mA and VLED voltage up to

150V. The PWM dimming, DC input analog

dimming and pulse analog dimming are all

included. The Over-Voltage protection, short

LED protection, short inductor/diode protection

and over current protection are integrated. The

fault pin goes to low when fault conditions are

detected.
