MP4013 High-Brightness, High-Current Accuracy WLED Controller The Future of Analog IC Technology FEATURES DESCRIPTION Constant-current WLED Driver The MP4013 is a current mode controller 600mV Feedback Voltage with 1.2% designed for driving the high brightness Light Accuracy Emitting Diodes (LEDs) with wide supply voltage 8V-26V Input Voltage 8V-26V. It can be used in Boost, Buck, Buck- Programmable Switching Frequency boost and SEPIC topologies. Leading Edge Blanking for Current Sense The MP4013 drives external MOSFET with fixed High Dimming Ratio Fast DPWM Dimming frequency architecture to regulate the LED DC Input or Pulse Signal Input Analog current, which is measured through an external Dimming current sense resistor. The switching frequency 5V Reference Voltage with 1% Accuracy can be programmed to meet kinds of External PWM Dimming MOS Driver applications. The cycle-by-cycle current limit can Programmable Input Bus Voltage UVLO be programmed by the sense resistor on CS pin. Soft Start The MP4013 integrates a 600mV reference Over Voltage Protection voltage for LED current feedback with 1.2% Short LED Protection accuracy. It outputs a 5V reference voltage with Short Output Protection 1% accuracy, which is used as the reference Over Current Protection voltage for external circuit. Short Inductor/Diode Protection Fault Indicator The MP4013 implements both DC input analog VIN UVLO dimming and pulse signal input analog dimming function. The amplitude of the LED current could Thermal Shutdown be controlled either by the level of a DC input Available in SOIC-16 package signal or by the duty cycle of a pulse signal. The APPLICATIONS MP4013 also employs fast and deep PWM dimming to the LED current with high dimming LCD Backlighting applications ratio. DC/DC LED Driver applications General Illumination MP4013 integrates Under-Voltage Lockout, Industrial Lighting Over Voltage Protection, Over Current Automotive/ Decorative LED Lighting Protection, Short LED Protection, Short Output Protection, Short Inductor/diode Protection and All MPS parts are lead-free and adhere to the RoHS directive.
