DESCRIPTION

The

BxxxxS-1W

series

of

DC/DC

Converters

is

particularly

suited

to

isolating

and/or

converting

DC

power

rails.

The

galvanic

isolation

allows

the

device

to

be

configured

to

provide

an

isolated

negative

rail

in

systems

where

only

positive

rails

exist.

The

wide

temperature

range

guarantees

startup

from

–40°C

and

full

1

watt

output

at

85°C.

For

lower

ripple,
