EVALUATION BOARD
DESCRIPTION
The EV2303DN-00A is an evaluation board for
the MP2303, a monolithic synchronous buck
regulator.
The MP2303 integrates 120mΩ MOSFETS that
provide 3A continuous load current over a wide
operating input voltage of 4.75V to 28V.
Current mode control provides fast transient
response and cycle-by-cycle current limiting. An
adjustable soft-start prevents inrush current at
turn-on. In shutdown mode, the supply current
drops to 0.3µA.
This device, available in an 8-pin SOIC
package, provides a very compact system
solution with minimal reliance on external
components.
