MP4013

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.
