2A, 16V, 340KHz Synchronous Rectified
Step-Down Converter
DESCRIPTION
The MP28313 is a monolithic synchronous buck
regulator. The device integrates 130m
MOSFETS that provide 2A continuous load
current over a wide operating input voltage of
5V to 16V. Current mode control provides fast
transient response and cycle-by-cycle current
limit.
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.
