AC / DC converter
BP5034D12
The BP5034D12 is an AC / DC converter which can be used to supply +12V, 100mA DC output from a commercial
power supply (100V AC). Using this module enables simple, easy drive of microcomputers, LEDs, and other electronic
components without using a transformer. It also allows set PCBs to be kept compact and lightweight, with extremely few
attachments.
!
!!
!Applications
Power supply circuits for vacuum cleaners, washing machines, refrigerators, electric carpets, electric rice cookers and
crock pots, irons, cordless telephones, air purifiers, humidifiers, dehumidifiers, illumination 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
!
!!
!Features
1) Elimination of a transformer enables compact, lightweight power supply boards.
2) Wide input voltage range. (80 to 138V for AC voltage conversion)
3) DC power supply can be easily configured, with few attachments.
4) Because no transformer is used, the power supply board is less vulnerable to splitting or cracking from impact or
shock.
5) Allow easy assemblage of componentes.

!Selecting attachment
(1) Diodes
The rectifying diodes used should fulfill the following conditions.
In the absolute maximum ratings, the reverse peak voltage should be 400V or higher, the average rectifying current
should be 0.5A or higher, and the forward peak surge current should be 20A or higher. For example, 1SR35-400A is
recommended.
(2) Smoothing capacitor for input pin
A capacitor with a larger capacitance produces a more stable output voltage, but increases the rush current when
the power supply is turned on. The capacitor should have a withstand voltage of at least 200V. Please refer to Fig.5
for examples of recommended capacitance values.

(3) Smoothing capacitor for output pin
This capacitor should have a low ESR. The low-impedance capacitors designed for switching power supplies are
especially suitable. The ESR of the capacitor affects the output ripple voltage.

!!
!Operation notes
(1) The output current needs to be reduced as the ambient temperature rises. (Refer to derating curve.)
(2) Lead pins should be securely soldered. If common pins are not securely connected, or pins which are connected
internally but which are not used are connected to other pins, irregular voltages could be produced, causing
breakdowns and damage.
(3) Over current and shorted circuit
The over current limit is a drooping model. If there is any danger of the load being shorted or over current being
produced, always use a protective device such as a fuse.
(4) Avoid subjecting this product to strong impact.
(5) Regulations on Electrical Appliances
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 secondary 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 provided.
