MONOLITHIC POWER SYSTEMS (MPS) MPQ7220GR-AEC1-P Datasheet & Stock

MPQ7220 is a boost converter with six channel current sources. It is designed for driving automotive tail lights. The MPQ7220 uses peak current mode as its PWM control architecture. The switching frequency can be programmed by a resistor. It independently regulates the current in each LED string to the value set by an external current-setting resistor. The device applies six internal current sources, one in each LED string terminal to achieve a current balance with 2.5% current regulation accuracy between strings. The low headroom voltage for LED regulation and on resistance of switching MOSFETs allows for high efficiency. The MPQ7220 has rich protection modes to guarantee safe operation. Protection modes include OCP (overcurrent protection), OVP (overvoltage protection), OTP (overtemperature protection) and LED string short and open protection. The LED current decreases at high temperatures. Used in automotive tail lights applications. Available in QFN-24 (4mmx4mm) package.
