3A, 1.5MHz, 28V
The Future of Analog IC Technology
The MP1584 is a high frequency step-down
switching regulator with an integrated internal
high-side high voltage power MOSFET. It
Wide 4.5V to 28V Operating Input Range
O Programmable Switching Frequency from
F 100kHz to 1.5MHz
provides 3A output with current mode control for
fast loop response and easy compensation.
D The wide 4.5V to 28V input range accommodates
a variety of step-down applications, including
those in an automotive input environment. A
E 100µA operational quiescent current allows use in
D S High power conversion efficiency over a wide
N 8 load range is achieved by scaling down the
E N switching frequency at light load condition to
3 reduce the switching and gate driving losses.
M IG 3 The frequency foldback helps prevent inductor
current runaway during startup and thermal
2 shutdown provides reliable, fault tolerant
M S operation.
P By switching at 1.5MHz, the MP1584 is able to
E prevent EMI (Electromagnetic Interference) noise
O M problems, such as those found in AM radio and
D ADSL applications.
