BP5035 / BP5035-5
Power Module
AC / DC converter
BP5035 / BP5035-5
The BP5035 and BP5035-5 are an AC / DC converters which can be used to supply DC output from a commercial
power supply (100V AC). Using these modules enables simple, easy drive of microcomputers, DC motors, heaters,
LEDs, and many other electronic components without using a transformer. They also allow 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 120Vrms for AC voltage conversion)
3) DC power supplies can be easily configured, with few attachments.
4) The output current is large, at 200mA.
5) +COMMON of -12V (BP5035) / -5V (BP5035-5) outputs are provided. These are ideal for TRIAC drive for AC control.
6) Because no transformer is used, the power supply board is less vulnerable to splitting or cracking from impact or
shock.
7) Allow easy assemblage of components.

!Selecting
attachments
(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.
(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. Make sure a capacitor of
22µF or higher is used for half wave rectification, and 6.8µF or higher for full wave rectification.
(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.
(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. At 25°C, if over current which exceeds the absolute maximum ratings is
produced intermittently, or is produced continuously for a total of one minute or longer, these products are vulnerable
to damage. 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 these products to strong impact.
(5) Regulations on Electrical Appliances
As stand-alone products, they are not subject to regulation governing electrical appliances. Please be aware,
therefore, that applications must be submitted for sets and not for individual products.
(6) Insulation
These products are not insulated on the primary and secondary sides, and there is a danger or electrical shock if they
are touched.
(7) Connections with other devices
Device using these products should not be connected to other devices. If connected, insulation should be provided.
(8) External I / O capacitors should be positioned as closes possible to pins, and coils should be positioned as follows.
