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.
