MPQ28261DL - 500kHz Synchronous Step-Down Converter

Download the MPQ28261DL datasheet PDF. This datasheet also covers the MPQ28261 variant, as both devices belong to the same 500khz synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MPQ28261 is a synchronous, rectified, step-down, switch-mode converter with built-in 120mΩ high-side MOSFET and 20mΩ low-side MOSFET.

It offers a very compact solution to achieve a continuous 3A output current over a wide input supply range, with excellent load and line regulation.

Key Features

  • include over-current protection and thermal shut down. The MPQ28261 has an external SS pin to program the soft-start time and power-good signal output. The MPQ28261 requires a minimal number of readily-available standard external components and is available in a space saving 3mmx4mm 14-pin QFN package.

MPQ28261 21V, 3A, 500kHz Synchronous Step-Down Converter DESCRIPTION The MPQ28261 is a synchronous, rectified, step-down, switch-mode converter with built-in 120mΩ high-side MOSFET and 20mΩ low-side MOSFET. It offers a very compact solution to achieve a continuous 3A output current over a wide input supply range, with excellent load and line regulation. Its synchronous mode operation increases its efficiency over its output current load range, and uses a fixed 500kHz switching frequency. Current mode operation provides a fast transient response and improves loop stabilization. Full protection features include over-current protection and thermal shut down. The MPQ28261 has an external SS pin to program the soft-start time and power-good signal output.
