DESCRIPTION

The

EV020-5-S-00D

Evaluation

Board

is

designed to demonstrate the capabilities of

MP020-5.

The

MP020-5

is

a

primary-side-control

regulator

which

can

eliminates secondary feedback components.

The EV020-5-S-00D is typically designed for

small appliances which output 18V/0.3A and

5V/0.1A

load

from

85VAC

to

265VAC,

50HZ/60HZ.

The EV020-5-S-00D has an excellent efficiency

and meets IEC61000-4-5 surge immunity and

EN55022 conducted EMI requirements. It has

multi-protection

function

as

open

circuit

protection, short-circuit protection, cycle by

cycle

current

limit

and

over-temperature

protection, etc.
