Product Overview

The EVQ3369-R-00A is an evaluation board for MPQ3369 in 24 pin QFN package. The MPQ3369 is a step-up converter with 6-channel current sources. It is designed for driving the white LED arrays as backlighting of middle or small size LCD panel. The MPQ3369 uses peak-current mode as its PWM control architecture to regulate the boost converter. 6 channel current sources are applied into the LED cathode to adjust the LED brightness. It 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. MPQ3369 employs a low on-resistor MOSFET and a low headroom voltage design to get the higher efficiency. It has standard I2C digital interface for easy use.
  • 3.5V to 36V input voltage range
  • Programmable up to 2.2MHz switching frequency
  • External sync SW function
  • 15000:1 dim ratio in PWM dim at Fpwm<=200Hz
  • 200:1 dim ratio at analogue dim thru PWM dim signal input
  • Excellent EMI performance, frequency spread spectrum
  • OCP, OVP, OTP, LED short and open protection
  • Programmable LED short threshold
  • Programmable OVP threshold
  • Fault indicator signal output
