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.
