AC / DC converter unit
BP5038
The BP5038 is an AC / DC converter which can be used to supply 12V, 30mA DC output from a commercial power supply
(100 V AC). Using this unit enables simple, easy drive of microcomputers, relays, LEDs, and many other electronic com-
ponents without using a transformer. The most compact of all of the products in the BP5030 series of AC / DC converters,
the BP5038 allows set PCBs to be kept compact and lightweight, with extremely few attachments.
FApplications
Power supply circuits for vacuum cleaners, electric car-
pets, electric rice cookers and hot water pots, irons, air
conditioners, air purifiers, humidifiers, dehumidifiers, illu-
mination devices and other small household appliances,
as well as power supply circuits for gas, fire and smoke
alarms, DC motors, sensors, and other similar devices
FFeatures
1) Elimination of a transformer enables compact, light-
weight power supply boards.
2) Wide input voltage range. (80 to 120Vrms for AC volt-
age conversion)
3) DC power supplies can be easily configured, with few
attachments.
4) Compact, stand-alone 4-pin SIP package.
5) Since no transformer is used, the power supply board
is less vulnerable to splitting or cracking from impact
or shock.
6) Hybridization of the IC reduces the number of labor
hours in the assembly process.

FSelecting attached components
(1) Diodes
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) Capacitor for input voltage smoothing
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.

(3) Capacitor for output voltage smoothing
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.
FOperation notes
(1) The output current needs to be reduced as the am-
bient temperature rises.
(2) Lead pins should be securely soldered. If COM-
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) Excessive current and shorted loads
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.
(4) Avoid subjecting this product to strong impact.
(5) Regulations governing electrical products
As a stand-alone product, this product is not subject to
regulations governing electrical appliances. Please be
aware, therefore, that applications must be submitted for
sets and not for individual products.
(6) Insulation
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) Connections with other devices
Devices using this product should not be connected to
other devices. If connected, insulation should be pro-
vided.
