MPQ3428A

The MPQ3428A is an automotive AECQ application device with 600kHz, fixed-frequency, high-efficiency, wide input range, current mode boost converter, 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.

With a programmable input average current limit, the MPQ3428A supports a wide range of applications, including eCall, Smart latch, Telematics and infotainment. The MPQ3428A features a 18mΩ, 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 under all conditions.

The MPQ3428A includes under-voltage lockout, switching current limiting, and thermal shutdown to prevent damage in the event of an output overload. The MPQ3428A is available in a low-profile QFN-22 (3mmx4mm) package.
