Product Overview

MP3367 is a step-up converter with six channel current sources, designed to drive white LED arrays as backlighting in small-to-mid-size LCD panels. It uses peak current mode as its PWM control architecture to regulate the boost converter. Six channel current sources are applied into the LED cathode to adjust the LED brightness. The MP3367 regulates current in each LED string to the value set by an external current-setting resistor with 2.5% current regulation accuracy between strings. The device employs a low on-resistor MOSFET and a low headroom voltage, designed for higher efficiency. The switching frequency can be programmed by a resistor, I2C interface or external clock. The MP3367 provides analogue, PWM and mix dimming mode with a PWM input. Robust protections are included to guarantee safe operation of the device. Protection modes include over-current protection, over-voltage protection, over-temperature protection, LED short open protection. Typically used in tablet/notebooks.
  • 3.5V to 36V input voltage range
  • Six channels with maximum 150mA per channel
  • Internal 100mohm, 50V MOSFET
  • Programmable up to 2.2MHz fSW, external sync SW function
  • Optional LED current auto-decrement at high temperatures
  • Multi-dimming operation mode through PWM input
  • 15000:1 dim ratio in PWM dim at fPWM <= 200Hz
  • 200:1 dim ratio at analogue dim through PWM dim signal input
  • Excellent EMI performance, frequency spread spectrum
  • Phase shift function for PWM dimming, I2C interface
