EV2309DS-00A
1A, 23V, 340KHz Synchronous
Step-Down Converter Evaluation Board
GENERAL DESCRIPTION
The EV2309DS-00A is an evaluation board for
the MP2309, a monolithic synchronous buck
regulator. The device integrates 140mΩ
MOSFETS that provide 1A 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.
An adjustable soft-start prevents inrush current
at turn-on. In shutdown mode, the supply
current is only 1µA.
This device, available in an 8-pin SOIC
package, provides a very compact system
solution with minimal reliance on external
components.
