The MPQ2933-AEC1 is a highly efficient, current-mode, synchronous buck controller with a wide input voltage (V_IN) range. The wide 3.6V to 36V V_IN range makes the device well-suited for multi-purpose automotive and industrial applications.

The MPQ2933-AEC1 uses pulse-width modulation (PWM) current control architecture with accurate cycle-by-cycle current limiting and can drive dual N-channel MOSFETs. Advanced asynchronous modulation (AAM) mode enables nonsynchronous operation to optimize light-load efficiency.

The switching frequency (f_SW) is resistor-configurable between 200kHz and 2.2MHz. The MPQ2933-AEC1 can also be synchronized to an external clock. Configurable frequency spread spectrum (FSS) improves EMI performance.

An open-drain power good (PG) signal indicates whether the output is within 94% to 106% of its nominal voltage.

Full protection features include precision output over-voltage protection (OVP), input over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown.

The MPQ2933-AEC1 is available in a QFN-38 (5mmx8mm) package.
