EVQ3369-R-01A is an evaluation board designed for the MPQ3369, 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 MPQ3369 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 IC employs a low on-resistance MOSFET and a low headroom voltage design to achieve high efficiency. It has a standard I2C digital interface for easy use. The MPQ3369 provides analogue, PWM, and mix dimming mode with PWM input. Protection features that guarantee safe operation include OCP, OVP, OTP, LED short and open protection. Applications includes tablets/notebooks and automotive displays.
