MPQ2189-AEC1

4A, 2.7V to 6V, High-Efficiency, Synchronous Step-Down Converter with Serial Interface, AEC-Q100 Qualified

Datasheet

Description

The MPQ2189 is a highly integrated, high-frequency, synchronous step-down converter with a serial interface. The MPQ2189 can support up to 4A of load current across an input voltage (V_IN) supply range from 2.7V to 6V, 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 V_OUT range can be adjusted from 0.6V to 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 MPQ2189 requires a minimal number of readily available, standard external components, and is available in a compact QFN-14 (2.5mmx3mm) package.
