HYBRID IC FOR ON-BOARD POWER SUPPLY

DESCRIPTION

The

YS243DD-12

thin-profile

and

lightweight

dual-output DC-DC converter. Its output power is 3W and

the input is insulated from the output. With an over-current

protection circuit built-in, the YS243DD-12 is an optimum

solution for onboard power supplies in FA, OA, and control

equipment.

HYBRID IC FOR ON-BOARD POWER SUPLY

FOR SAFETY USING

Great detail and careful attention are given to the production activity of Hics, such as the development, the quality of production,

and in it’s reliability. However the reliability of Hics depends not only on their own factors but also in their condition of usage.

When handling Hics, please note the following cautions.

CAUTIONS

Packing

The materials used in packing Hics can only withstand normal external conditions.

When exposed to outside shocks, rain and certain environmental contaminators, the packing

materials will deteriorates. Please take care in handling.

Don’t stack boxes too high. Avoid placing heavy materials on boxes.

Boxes must be positioned correctly during transportation to avoid breakage.

Don't throw or drop boxes.

Keep boxes dry. Avoid rain or snow.

Minimal vibration and shock during transportation is desirable.

Carrying

Storage

When storing Hics, please observe the following notices or possible deterioration of their electrical

characteristics, risk of solderability, and external damage may occur.

1) Devices must be stored where fluctuation of temperature and humidity is minimal, and must

not be exposed to direct sunlight. Store at the normal temperature of 5 to 30 degrees Celsius

with humidity at 40 to 60%.

2) Avoid locations where corrosive gasses are generated or where much dust accumulates.

3) Storage cases must be static proof.

4) Avoid putting weight on boxes.

When extended storage is necessary, Hics must be kept non-processed. When using Hics which

have been stored for more than one year or under severe conditions, be sure to check that the

exterior is free from flaw and other damages.

To prevent any electrical damages, use Hics within the maximum ratings.

current, voltage, etc. must not exceed these conditions.

Polarity

To protect Hics from destruction and deterioration due to wrong insertion, make sure of polarity in

inserting leads into the board holes, conforming to the external view for the terminal arrangement.
