DESCRIPTION

The EV9447-L-00A is an evaluation board for

the

MP9447,

a

high-efficiency

step-down

regulator with integrated power MOSFETs.

MP9447 offers a very compact solution to

achieve a 5A, continuous-output current over a

wide input-supply range with excellent load and

line regulation. It also provides fast transient

response and good stability for wide input-

supply and load range.

The EV9447-L-00A is a fully assembled and

tested evaluation board. It generates a +5V

output voltage at load current up to 5A from a

7V to 36V input range. Switching frequency is

set at 500kHz.
