| The BP5074 series AC/DC converters with low power consumption during standby. (7mW - a decrease of at least 75% over previous units) High efficiency AC/DC converters (BP5074 series) have been developed in a microcontroller application). In addition, the only external with a power consumption of 7mW during standby (1/4 that of conventional products) and less than 50mW during operation at light loads (e.g. 2mA components required are input/output capacitors and a rectifier diode. The entire series is Lead-free and RoHS compliant. Features Standby power consumption = 7mW Input AC 100V Output DC12V, 0mA Dimensions BP5074 Marking Side (UNIT : mm) EFFICIENCY Conversion effciency 80% Transformer Type BP5034 BP5074 Conventional EFFICIENCY [] 70% 60% 50% 40% 30% 20% 10% 0% 0 10 20 30 40 50 60 70 80 90 100 OUTPUT CURRENT [mA] Simple configuration with internal coil. The only external components required are input/output capacitors and a rectifier diode. Greater efficiency during lighter loads. 17% improvement in efficiency during light loads BP5074 Conventional *Contact ROHM for more information on these products.
