Manufacturer Part Number
bp5038
Description
Ac / Dc Converter Unit
Manufacturer
ROHM Co. Ltd.
Datasheet
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-
