Product Description

The MP9184 is a 600kHz, 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 applications. With a current limit above 17A, the MP9184 supports a wide range of applications, including POS, Thunderbolt, Bluetooth Audio, Power Banks, and Fuel Cells. The MP9184 features a 10mΩ, 24V power switch and a synchronous gate driver for high efficiency. An external compensation pin gives the user flexibility in setting loop dynamics and obtaining optimal transient performance at all conditions.
The MP9184 includes under-voltage lockout (UVLO), switching-current limiting, and thermal shutdown (TSD) to prevent damage in the event of an output overload.
The MP9184 is available in a low-profile 22-pin 3mm x 4mm QFN package.
