DESCRIPTION
The EV2305DS-00A is the evaluation board of
MPSâ MP2305 synchronous buck converter. It
has a wide supply range from 4.75V to 23V and
a continuous output current up to 2A. It features
synchronous rectification for high efficiency with
integrated high-side and low-side power
MOSFETs. The output voltage is preset to 3.3V,
but can be easily adjusted to other levels from
0.923V. Current mode control and integrated
power MOSFETs minimize component counts,
board area, and solution cost. Fault condition
protections include cycle-by-cycle current limiting,
thermal shutdown and under-voltage lockout.
Programmable soft-start reduces turn-on stress.
Small SO-8 package minimizes board area.
