GENERAL DESCRIPTION
The EV1570DN-00A is the evaluation board of
MPS’ MP1570 synchronous buck converter. It
has a wide supply range from 4.75V to 23V and
a continuous output current up to 3A. It features
synchronous rectification for high efficiency with
integrated
high-side
MOSFETs. The output voltage is set to 3.3V,
but can be easily adjusted to other levels from
1.22V. 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, over voltage protection and
under voltage lockout. Internal soft-start reduces
turn-on stress. Small but thermally enhanced
SO-8 package minimizes board area with
excellent thermal management.
