BP5041
The BP5041 is an AC / DC converter which can be used to supply )12V, 100mA DC output from a commercial power
supply (200 to 230V AC). Using this unit enables simple, easy drive of microcomputers, LEDs, and other electronic com-
ponents without using a transformer. It also allows set PCBs to be kept compact and lightweight, with extremely few
attachments.
This product can accommodate the 200V AC power supplies used as household power supplies in Asia and Europe,
as well as in buildings and facilities in Japan.
FApplications
Power supply circuits for vacuum cleaners, refrigerators,
washing machines, air conditioners, irons, electric car-
pets, cordless telephones, air purifiers, humidifiers, de-
humidifiers, home bakery devices, electric hot water pots
and rice cookers, illumination devices and other small
household appliances, as well as power supply circuits
for gas leakage sensors, and other industrial products
FFeatures
1) Elimination of a transformer enables compact, light-
weight power supply boards.
2) Wide input voltage range. (226 to 358V DC for DC
voltage conversion, 160 to 253V for AC voltage con-
version)
3) DC power supplies can be easily configured, with few
attachments.
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.
