The Future of Analog IC Technology
The MP148 2 is a monolithic synchr onous buck
regulator. T he device integrates t wo 130m Ω
MOSFETs, and provides 2A of cont inuous load
current over a wide input voltage of 4.75V to
18V. Current mode control pro
transient re sponse and cycle-by-cycle current
An adjustab le soft-start prevents inrush current
at turn-on, and in shut down mode the supply
current drops to 1µA.
This device, available in an
8-pin SOI C
package, provides a very compact solution with
minimal external components.
