MPQ9841GL - Synchronous Step-Down Converter

Download the MPQ9841GL datasheet PDF. This datasheet also covers the MPQ9841 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 MPQ9841 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs.

It offers a very compact solution that achieves 1A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range.

Key Features

  • include over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown. An open-drain power good (PG) signal indicates when the output is within 10% of its nominal voltage. The MPQ9841 is available in a space-saving QFN-16 (3mmx4mm) package.

The Future of Analog IC Technology DESCRIPTION The MPQ9841 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution that achieves 1A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range. The switching frequency can be programmed or synchronized to an external clock in the range of 350kHz to 2.5MHz. The synchronous operation and ultralow 14μA sleep mode quiescent current provide high efficiency over the output current load range, allowing the MPQ9841 to be used in a variety of step-down applications in automotive input environments and battery-powered applications.
