MPQ3364-AEC1 Part Attribute
- Description The 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 (fSW) can be configured via a resistor, I2C interface, or external clock. The MPQ3364 provides analog, PWM, and mix dimming modes with a PWM input. The dimming mode can be selected via the I2C interface or the MIX/AD pin. The device also has a phase shift function to eliminate noise during PWM dimming. Robust protections are included to guarantee safe operation of the device. Protection modes include over-current protection (OCP), overvoltage protection (OVP), over-temperature protection (OTP), LED short, and LED open protection. The MPQ3364 can automatically decrease the LED current at higher temperatures. The MPQ3364 is available in a QFN-24 (4mmx4mm) package.
