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. Applications 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 Features 1) Elimination of a transformer enables compact, light- 4) Since no transformer is used, the power supply board weight power supply boards. is less vulnerable to splitting or cracking from impact 2) Wide input voltage range.
