• Manufacturer: ROHM Co. Ltd.

FSelecting attached components
(1)
The rectifying diodes used should fulfill the following
conditions.
In the absolute maximum ratings, the reverse surge cur-
rent should be 400V or higher, the average rectifying cur-
rent should be 0.5A or higher, and the forward surge volt-
age should be 20A or higher.
(2)
A capacitor with a larger capacitance produces a more
stable output voltage, but increases the surge current
when the power supply is turned on. The capacitor
should have a withstand resistance of at least 200V.
FOperation notes
(1)
bient temperature rises.
(2)
MON pins are not securely connected, or pins which are
connected internally but which are not used are con-
nected to other pins, irregular voltages could be pro-
duced, causing breakdowns and damage.
(3)
The excessive current limit is a drooping model. At 25_C,
if excessive current which exceeds the absolute maxi-
mum ratings is produced intermittently, or is produced
continuously for a total of one minute or longer, the prod-
uct is vulnerable to damage. If there is any danger of the
load being shorted or excessive current being produced,
always use a protective device such as a fuse.

This capacitor should have a low ESR. Capacitors de-
signed for low-impedance switching power supplies are
especially suitable. The ESR of the capacitor affects the
output ripple voltage. Please refer to the table below for
the names of products made by various manufacturers.
(6)
This product is not insulated on the primary and second-
ary sides, and there is a danger of electrical shock if it is
touched.
(7)
Devices using this product should not be connected to
other devices. If connected, insulation should be pro-
vided.
