DESCRIPTION
EV3414A-J-00A Evaluation Board is designed
to demonstrate the capability of MP3414A. The
MP3414A is a high-efficiency, synchronous,
current-mode, step-up converter with output
disconnect.
The MP3414A provides inrush current limiting
and output short-circuit protection. The
integrated, P-channel, synchronous rectifier
improves efficiency and eliminates the need for
an external Schottky diode. The PMOS
disconnects the output from the input when the
part shuts down.
The 1MHz switching frequency allows for small
external components, while the internal
compensation and the soft-start minimize the
external component count. The MP3414A is
available in a small 8-pin TSOT23 package.
