The MPQ2180 is a highly integrated, high-frequency, synchronous step-down converter with a serial control interface. The MPQ2180 can support up to 6A of load current across a 2.7V to 6V input voltage (V_IN) range, with excellent load and line regulation.

Constant-frequency hysteretic mode provides an extremely fast transient response without loop compensation to achieve high efficiency under light-load conditions. The output voltage (V_OUT) can be controlled on-the-fly via a 3.4Mbps serial interface. The voltage range can be adjusted between 0.6V and 1.235V in 5mV steps. The V_OUT slew rate, switching frequency (f_SW), and power-save mode can be configured via the serial interface.

Full protection features include internal soft start (SS), over-current protection (OCP), and thermal shutdown.

The MPQ2180 requires a minimal number of readily available, standard external components, and is available in a compact QFN-14 (2.5mmx3mm) package.
