Product Overview
MPQ3364 is a step-up converter with 4 channel current sources. The device 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. Four channel current sources are applied to the LED cathode to adjust LED brightness. The MPQ3364 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. A low on resistance MOSFET and headroom voltage are provided to improve efficiency. The MPQ3364 has a standard I2C digital interface for easy use. The switching frequency can be configured via a resistor, I2C interface, or external clock The MPQ3364 provides analogue, PWM and mix dimming modes with a PWM input. The MPQ3364 is available in a QFN-24 (4mmx4mm) package. Applications include tablets, notebooks and automotive displays.
- Available in AEC-Q100 grade 1, 3.5V to 36V input voltage, 4 channels with maximum 150mA per channel
- Internal 100mohm, 50V MOSFET, configurable fSW up to 2.2MHz, external sync SW function
- Multi-dimming operation through PWm input
- 15000:1 dimming ratio in PWM dimming when fPWM ≤ 200Hz
- 200:1 dimming ratio during analogue dimming through PWM dimming signal input
- Excellent EMI performance, frequency spread spectrum
- I2C interface with 3 selectable IC addresses
- Phase shift function for PWM dimming, 2.5% current matching
- Cycle-by-cycle current limiting, disconnect VOUT from VIN
- LED short/open, OTP, OCP and inductor short protection
