MPQ3369GR - Maximum 100mA/Ch Boost WLED Driver

Download the MPQ3369GR datasheet PDF. This datasheet also covers the MPQ3369 variant, as both devices belong to the same maximum 100ma/ch boost wled driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The MPQ3369 is a step-up converter with six channel current sources.

It is designed to drive 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.

DESCRIPTION The MPQ3369 is a step-up converter with six channel current sources. It is designed to drive 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 into the LED cathode to adjust the LED brightness. The MPQ3369 regulates the current in each LED string to the value set via an external current-setting resistor, with 2.5% current regulation accuracy between strings. A low on resistor MOSFET and a low headroom voltage are provided to improve efficiency. The MPQ3669 has a standard I2C digital interface for easy use. The switching frequency can be configured via a resistor, I2C interface, or external clock.
