MPQ3428A-AEC1

The MPQ3428A 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 prevent battery depletion.

With a programmable input average current limit, the MPQ3428A supports a wide range of applications, including POS, Thunderbolt, Bluetooth audio, power banks, and fuel cells.

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.
