Product Overview

MP3364 is a step-up converter with four channel current sources. It is designed to drive white LED arrays as backlighting for small- or medium-sized LCD panels. Device uses peak current mode as its PWM control architecture to regulate the boost converter. Four channel current sources are applied to the LED cathode to adjust the LED brightness. MP3364 regulates the current in each LED string to the value set by an external current-setting resistor with 2.5% current regulation accuracy between strings. A low on resistance MOSFET and headroom voltage are provided to improve efficiency. The MP3364 has a standard I2C digital interface for easy use. Switching frequency can be configured via a resistor, I2C interface or external clock. The MP3364 provides analogue, PWM and mixed dimming modes with a PWM input. Robust protections included to guarantee safe operation. MP3364 can automatically decrease LED current at higher temperatures. The MP3364 is available in a QFN-24 (4mmx4mm) package.
  • 3.5V to 36V input voltage range, 4 channels with maximum 150mA per channel
  • Internal 100mohm, 50V MOSFET, configurable fSW up to 2.2MHz, external sync SW function
  • Multi-dimming operation mode through PWM I/P, dimming mode can be selected by I2C or MIX/AD pin
  • 15000:1 dimming ratio during PWM dimming when fPWM <= 200Hz
  • 200:1 dimming ratio during analogue dimming through PWM dimming signal input
  • Excellent EMI performance, frequency spread spectrum, can be used in tablets and notebooks
  • I2C interface, 3 selectable IC addresses, phase shift function for PWM dimming
  • 2.5% current matching, cycle-by-cycle current limiting, disconnect VOUT from VIN
  • LED short/open, OTP, OCP, OVP and inductor short protection
  • Configurable LED short threshold, configurable OVP threshold, fault indicator signal output
