Product Overview

EVQ3367-R-01A is an evaluation board designed for the MPQ3367, a step-up converter with six channel current sources. It is designed to drive the white LED arrays as backlighting for small- or medium-sized LCD panels. The device uses peak current mode as its PWM control architecture to regulate the boost converter. Six channel current sources are applied to the LED cathode to adjust the LED brightness. The MPQ3367 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. The MPQ3367 has a standard I2C digital interface for easy use. The MPQ3367 provides analogue, PWM, and mix dimming mode with a PWM input. Protection features that guarantee safe operation include OCP, OVP, OTP, LED short and open protection. The MPQ3367 is available in QFN-24 (4mmx4mm) and TSSOP-28EP packages. Applications includes tablets/notebooks and automotive displays.
  • 3.5V to 36V input voltage range, 6 channels with 150mA max per channel
  • Internal 100mohm, 50V MOSFET, up to 2.2MHz configurable switching frequency (fSW)
  • 15000:1 dimming ratio during PWM dimming when fPWM ≤ 200Hz, 12V input voltage, <50V O/P voltage VLED
  • 200:1 dimming ratio during analogue dimming via PWM dimming signal input
  • Excellent EMI performance, frequency spread spectrum
  • I2C Interface, phase shift function for PWM dimming
  • 2.5% current matching, cycle-by-cycle current limiting, disconnect VOUT from VIN
  • Configurable LED short threshold and overvoltage (OV) threshold
  • Switching frequency (fSW) can be configured via a resistor, I2C interface or external clock
  • Fault indicator signal output
