Product 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.

The MP4013 is a current mode controller designed for driving the high brightness Light Emitting Diodes (LEDs) with wide supply voltage 8V-26V. It can be used in Boost, Buck, Buck-boost and SEPIC topologies.
The MP4013 drives external MOSFET with fixed frequency architecture to regulate the LED current, which is measured through an external current sense resistor. The switching frequency can be programmed to meet kinds of applications. The cycle-by-cycle current limit can be programmed by the sense resistor on CS pin.
The MP4013 integrates a 600mV reference voltage for LED current feedback with ±1.2% accuracy. It outputs a 5V reference voltage with ±1% accuracy, which is used as the reference voltage for external circuit.
The MP4013 implements both DC input analog dimming and pulse signal input analog dimming function. The amplitude of the LED current could be controlled either by the level of a DC input signal or by the duty cycle of a pulse signal. The MP4013 also employs fast and deep PWM dimming to the LED current with high dimming ratio.
MP4013 integrates Under-Voltage Lockout, Over Voltage Protection, Over Current Protection, Short LED Protection, Short Output Protection, Short Inductor/diode Protection and OTP. The fault indicator is pulled low in fault condition.
The MP4013 is available in SOIC-16 package.
