GENERAL DESCRIPTION
The MP2307 is a monolithic synchronous buck
regulator. The device integrates 100m
MOSFETS that provide 3A continuous load
current over a wide operating input voltage
range of 4.75V to 23V. Current mode control
provides fast transient response and cycle-by-
cycle current limit.
An adjustable soft-start prevents inrush current
at turn-on. In shutdown mode, the supply
current drops to only 1µA.
This device, available in an 8-pin SOIC
package, provides a very compact system
solution with minimal reliance on external
components.
