GENERAL DESCRIPTION
The EV1517DR-00A is the evaluation board for
the MP1517, a 3A, fixed frequency step-up
converter ideal for medium-to-high current
step-up
applications.
switching frequency allows for smaller external
components producing a compact solution for
size constrained cameras, PDAs and cell
phones. The low 0.7V feedback voltage offers
higher
efficiency
in
applications including cell phone camera flash.
The MP1517 regulates the output voltage up to
25V with efficiencies greater than 90%.
Soft-start, cycle-by-cycle current limiting, and
input
under
voltage
overstressing or damage to sensitive external
circuitry at startup and output short-circuit
conditions.
Current-mode
external compensation components allow the
MP1517 control loop to be optimized over a
wide variety of input voltage, output voltage,
and load current conditions. The MP1517 is
available in the thermally enhanced QFN16
(4mm x 4mm) package.
