Product Description

The MP9184A 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 battery-operated applications, this feature also helps in preventing battery depletion. With a programmable input average current limit, the MP9184A supports a wide range of applications, including POS, Thunderbolt, Bluetooth Audio, Power Banks, and Fuel Cells. The MP9184A 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 MP9184A includes under-voltage lockout, switching current limiting, and thermal shutdown to prevent damage in the event of an output overload.
The MP9184A is available in a low-profile QFN-22 (3mm x 4mm) package.

19A, 600kHz 20V Wide Input Synchronous Boost Converter EV Board

The EV9184A-L-00A Evaluation Board is designed to demonstrate the performances of MPS’ MP9184A, which has excellent protection and can provide load with12V/2A power from typical 3.3V input.

The MP9184A is a 600 kHz fixed frequency, high efficiency, wide input range, current mode boost converter with optional internal or external current sensing configuration for high integration and high power application. It features internally a 10mΩ, 24V power switch and a synchronous gate driver for high conversion efficiency. The MP9184A is available in a low profile 22-pin 3mmx4mm QFN package.

This board is configured for 12V application, the maximum output current is determined by current limit, permitted temperature rising and input voltage.
