| BP5048 / BP5048-15 / BP5048-24 Power Module AC / DC Converter BP5048 / BP5048-15 / BP5048-24 The BP5048, BP5048-15 and BP5048-24 are AC / DC converters which can be used to supply DC output from a commercial power supply (200 to 220 V AC). Using these modules enable simple, easy drive of microcomputers, LEDs, and other electronic components without using a transformer. They also allow set PCBs to be kept compact and lightweight, with extremely few attachments. These products 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 carpets, cordless telephones, air purifiers, humidifiers, dehumidifiers, home bakery devices, electric crock 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, lightweight power supply boards. 2) Wide input voltage range.(249 to 358V DC for DC voltage conversion) 3) DC power supplies can be easily configured, with few attachments. 4) Because no transformer is used, the power supply board is less vulnerable to splitting or cracking from impact or shock. 5) Allow easy assemblage of components. !List of the BP5048 series BP5048 Power supply voltage Output voltage Output current 249~358 12 300 BP5048-15 249~358 15 200 BP5048-24 249~358 24 200 Unit V V mA !Absolute maximum ratings (Ta=25C) Parameter Power supply voltage Operating temperature range Storage temperature range Symbol VIN Topr Tstg Limits 358 -20~+80 -25~+105 Unit V C C !Recommended operating conditions (Ta=25C) Parameter Power supply voltage Symbol VIN Min. 249 Typ. 311 Max. 358 Unit V(DC) BP5048 / BP5048-15 / BP5048-24 Power Module !Block diagram 5 12 Switching circuit 3 Current detector 1 Drive circuit Voltage detector 7 Note : Connect coil externally !Pin descriptions Pin No. 1 3 5 7 10 12 Pin name VOUT COIL COIL COMMON NC VIN Pins 2, 4, 6, 8, 9,11 are removed !Electrical characteristics (Unless otherwise noted, Ta=25C) BP5048 Parameter Input voltage Output voltage Output current Line regulation Load regulation Output ripple voltage Conversion efficiency Symbol VIN VO IO Vr Vl Vp Min. 249 11.0 0 -0.20 -0.20 - 65 Typ. 311 12.0 - 0.05 0.05 0.07 78 Max. 358 13.0 300 +0.20 +0.20 0.15 - Unit V V mA V V VPP % DC VIN=311V, Io=100mA VIN=311V VIN=249~358V, Io=100mA VIN=311V, Io=0~100mA VIN=311V, Io=100mA VIN=311V, Io=300mA 2 Conditions 1 1 Maximum output current varies depending on ambient temperature ; please refer to derating curve. 2 Spike noise is not included in output ripple voltage.

(2) Over current and shorted circuit The overcurrent protection circuit limits the current to about 330mA (BP5048), 240mA (BP5048-15), 230mA (BP5048-24) with drooping model. If there is any danger of the load being shorted or overcurrent being produced, always use a protective device such as a fuse. (3) Insulation These products are not insulated on the primary side, and there is a danger of electrical shock if they are touched. (4) Avoid subjecting these products to strong impact. (5) Lead pins should be securely connected. If lead pins are not securely connected, irregular voltages could be produced, causing breakdowns and damage.
