DESCRIPTION

The EV9473-L-00A is an evaluation board for

the MP9473, a high-efficiency step-down

regulator with integrated power MOSFETs.

MP9473 offers a very compact solution to

achieve a 3.5A, 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 EV9473-L-00A is a fully assembled and

tested evaluation board. It generates a +3.3V

output voltage at load current up to 3.5A from a

7V to 36V input range. Switching frequency is

set at 500kHz.
