The BP5040 is an AC / DC converter which can be used to supply
5V, 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 components without using a transformer. It also allows set PCBs to be kept compact and lightweight, with extremely few attachments.

Features
1) Elimination of a transformer enables compact, lightweight power supply boards.
2) Wide input voltage range (226 to 358V DC for DC voltage conversion, 160 to 253V for AC voltage conversion)
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.

Applications
    Power supply circuits for vacuum cleaners, refrigerators, washing machines, air conditioners, irons, electric carpets, cordless telephones, air purifiers, humidifiers, dehumidifiers, 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
