MPS MPQ2908A

MPS MPQ2908A - 4V-60V input, current mode, synchronous, step-down controller, AEC-Q100 qualified

MPS MPQ2908A package variations

The MPQ2908A is a high-voltage, synchronous, step-down controller that directly steps down voltages from up to 60V. The MPQ2908A 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 MPQ2908A 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.
