DESCRIPTION

The EV4470-L-01A is an evaluation board for

the MP/MPQ4470, while EV4470A-L-01A is an

evaluation board for the MP/MPQ4470A.

MP/MPQ4470 and MP/MPQ4470A are high-

efficiency step-down regulator with integrated

power MOSFETs. They offer a very compact

solution to achieve a 5A, continuous-output

current over a wide input-supply range with

excellent load and line regulation. They also

provide fast transient response and good

stability for wide input-supply and load range.

MP/MPQ4470

have

OVP

latch

while

MP/MPQ4470A have no this function.

The EV4470-L-01A and EV4470A-L-01A are

fully assembled and tested evaluation boards.

They generate +3.3V output voltage at load

current up to 5A from a 4.5V to 36V input range.

Switching frequency of both boards are set at

500kHz.
