DESCRIPTION
The EV0034 is a MP1527 evaluation board
configured to provide a regulated 12V output at
up to 300mA from a 2.6V input or higher. The
output voltage is adjustable from V
IN
to 25V by
changing resistors on the evaluation board.
The MP1527 has a high 1.3MHz switching
frequency that allows for smaller external
components, producing a compact solution for
medium-to-high current step-up, flyback, and
SEPIC applications.
