MP3428AGL - Synchronous Boost Converter

Download the MP3428AGL datasheet PDF. This datasheet also covers the MP3428A variant, as both devices belong to the same synchronous boost converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP3428A is a 600kHz, fixed frequency, high-efficiency, wide input range, current-mode boost converter with optional input disconnect and an input average current limit function.

Key Features

  • a 10mΩ, 24V power switch and a synchronous gate driver for high efficiency. An external compensation pin allows flexibility in setting loop dynamics and obtaining optimal transient performance at all conditions. The MP3428A includes under-voltage lockout, switching current limiting, and thermal shutdown to prevent damage in the event of an output overload. The MP3428A is available in a low-profile QFN-22 (3mm x 4mm) package. MP3428A 19A, 600kHz, 20V Wide Input Range, Synchronous Boost Converter.

The Future of Analog IC Technology DESCRIPTION The MP3428A is a 600kHz, fixed frequency, high-efficiency, wide input range, current-mode boost converter with optional input disconnect and an input average current limit function. The input disconnect feature provides additional protection by isolating the input from the output during output short or shutdown. For batteryoperated applications, this feature also helps in preventing battery depletion. With a programmable input average current limit, the MP3428A supports a wide range of applications, including POS, Thunderbolt, Bluetooth Audio, Power Banks, and Fuel Cells. The MP3428A features a 10mΩ, 24V power switch and a synchronous gate driver for high efficiency.
