DESCRIPTION
The MP2305 is a monolithic synchronous buck
regulator.
The
device
MOSFETS that provide 2A continuous load
current over a wide operating input voltage of
4.75V to 23V. Current mode control provides
fast transient response and cycle-by-cycle
current limit.
integrates
130m
An adjustable soft-start prevents inrush current
at turn-on. Shutdown mode drops the supply
current to 1μA.
This device, available in an 8-pin SOIC
package, provides a very compact system
solution with minimal reliance on external
components.
