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.
