BP5038 datasheet pdf

20 Regulator ICs AC / DC converter unit BP5038 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.
Applications 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
Features 1) Elimination of a transformer enables compact, light- weight power supply boards. 2) Wide input voltage range. (80 to 120Vrms for AC volt- age conversion) 3) DC power supplies can be easily configured, with few attachments. 4) Compact, stand-alone 4-pin SIP package. 5) Since no transformer is used, the power supply board is less vulnerable to splitting or cracking from impact or shock. 6) Hybridization of the IC reduces the number of labor hours in the assembly process.
