MPQ2179GQHE - Synchronous Step-Down Converter

Download the MPQ2179GQHE datasheet PDF. This datasheet also covers the MPQ2179 variant, as both devices belong to the same synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MPQ2179 is a monolithic, step-down switch-mode converter with built-in internal power MOSFETs.

The device achieves 3A of peak output current from a 2.5V to 5.5V input voltage range, with excellent load and line regulation.

The output voltage can be regulated to as low as 0.6V.

DESCRIPTION The MPQ2179 is a monolithic, step-down switch-mode converter with built-in internal power MOSFETs. The device achieves 3A of peak output current from a 2.5V to 5.5V input voltage range, with excellent load and line regulation. The output voltage can be regulated to as low as 0.6V. Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The MPQ2179 is ideal for a wide range of applications, including automotive infotainment systems, clusters, and telematics. The MPQ2179 requires a minimal number of readily available, standard external components, and is available in an ultra-small QFN-8 (1.5mmx2mm) package. MPQ2179 5.5V, Peak 3A, 2.
