About This Product

■Summary

MPQ3367 is a step-up converter with 6 channels of current sources. Designed to drive white LED arrays as backlights for small and medium-sized LCD panels. The MPQ3367 uses peak current mode as a PWM control architecture to regulate the boost converter. A 6-channel current source is applied to the LED cathode to adjust the LED brightness. Adjusts the current in each LED string to the value set by an external current setting resistor. String-to-string current regulation accuracy is 2.5%. MPQ3367 employs low on-resistance MOSFET and low headroom voltage design for higher efficiency. Equipped with a standard I2C digital interface, easy to use. Switching frequency is programmable by resistor, I2C interface, or external clock. MPQ3367 provides analog/PWM/mixed dimming modes with PWM input. Dimming mode can be selected by I2C interface or MIX/AD pin. It also has a phase shift function that eliminates noise during PWM dimming. Extensive protection features are designed to ensure safe operation. Protection modes include OCP (over current protection), OVP (over voltage protection), OTP (over temperature protection), and LED short circuit/open protection. Additionally, there is an option for the LED current to automatically decrease at higher temperatures. The MPQ3367 is available in QFN-24 (4mm x 4mm) and TSSOP28-EP packages.
