Description
The MPQ2918 is a high-voltage, synchronous, step-down controller that steps down voltages directly from up to 40V. The MPQ2918 uses pulse-width modulation (PWM) current control architecture with accurate cycle-by-cycle current limiting and is capable of driving dual N-channel MOSFETs.
Advanced asynchronous mode (AAM) enables non-synchronous operation to optimize light-load efficiency.
The operating frequency of the MPQ2918 can be programmed by an external resistor or synchronized to an external clock for noise-sensitive applications. Full protection features include precision output over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown.
The MPQ2918 is available in TSSOP20-EP and QFN-20 (3mmx4mm) packages.
