Product Overview

EVQ3364-R-00A is an evaluation board designed to demonstrate the capabilities of the MPQ3364, a four-channel step-up converter designed to drive white LED (WLED) arrays as backlighting for small or mid-sized liquid-crystal display (LCD) panels. Peak-current control is used as the pulse-width modulation (PWM) control architecture for regulating the boost converter. Four channel current sources are applied to the LED cathode to adjust the LED brightness. This 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 maximum current per channel is 150mA. The MPQ3364’s low on resistance MOSFET and low headroom voltage design improves efficiency. The device also has a standard digital I2C interface for easy flexibility. The MPQ3364 features three dimming modes: analogue dimming, PWM dimming, and mixed dimming via the PWM input. Applications include tablets, notebooks and automotive displays.
  • 3.5V to 36V input voltage range, 4 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 signal input
  • Excellent EMI performance, frequency spread spectrum
  • 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
  • Configurable LED short threshold and overvoltage (OV) threshold
  • Switching frequency (fSW) can be configured via a resistor, I2C interface or external clock
  • Available in AEC-Q100 Grade 1
