MPS EV1477-TF-00B Quick Start Manual

DESCRIPTION

The EV1477-TF-00B
designed to demonstrate the capabilities of
MPS' MP1477, a fully-integrated high-frequency,
synchronous rectified, step-down, switch-mode
converter with internal power MOSFETs. It
offers a very compact solution to achieve a 3A
continuous output current over a wide input
range, with excellent load and line regulation.
The MP1477 has synchronous-mode operation
for higher efficiency over the output current-load
range.
Constant On-Time control operation provides
very fast transient response and easy loop
design as well as very tight output regulation.
Full protection features include SCP, OCP,
UVP, and thermal shutdown.
The MP1477 requires a minimal number of
readily-available,
components and is available in a space-saving
SOT563 (1.6mmх1.6mm) package.
