MP9184A
19A, 600kHz, 20V Wide Input Range,
Synchronous Boost Converter
with Input Disconnect Function
The Future of Analog IC Technology
DESCRIPTION
FEATURES
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
3V to 20V Wide Input Range

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.
