AC / DC converter unit
BP5034A12
The BP5034A12 is an AC / DC converter which can be used to supply 12V, 100mA DC output from a commercial pow-
er supply (100V AC). Using this unit enables simple, easy drive of microcomputers, LEDs, and other electronic compo-
nents without using a transformer. It also allows set PCBs to be kept compact and lightweight, with extremely few attach-
ments.
Applications
Power supply circuits for vacuum cleaners, washing machines, refrigerators, electric carpets, electric rice cookers and
hot water 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, light-
weight power supply boards.
2) Wide input voltage range. (80 to 120V for AC voltage
conversion)
3) DC circuits can be easily configured, with few attach-
ments.
4) Since no transformer is used, the power supply board
is less vulnerable to splitting or cracking from impact
or shock.
5) Hybridization of the IC reduces the number of labor
hours in the assembly process.
