BD7F100EFJ-LB Datasheet | ROHM

Description This product guarantees long time supply availability in the industrial instrumentation market. BD7F100 is an optocoupler-less Isolated Flyback Converter. An optocoupler or the tertiary winding feedback circuit which was needed to obtain a stable output voltage isolated by a transformer in the conventional application bees unnecessary, thus, the number of parts is reduced drastically, producing a small-sized and high-reliability application isolated type power supply. Furthermore, a highly by the use of the Original Adapted-Type ON-Time Control Technology, it makes the external phase pensation parts bee unnecessary, therefore a highly efficient isolated type power supply application can easily be produced. Key Specifications - Supply Voltage of Operation: - SW Terminal Operating Voltage: - Over Current Limit: - Switching Frequency: - Reference Voltage Accuracy: - Quiescent Current: - Operating Current: - Junction Temperature of Operation: 3V to 40V 50V (Max) 1.25A (Typ) 400k Hz (Typ) ±1.5% 0µA (Typ) 2m A (Typ) -40°C to +125°C Packages HSON8 HTSOP-J8 W(Typ) D(Typ) H(Max) 2.90mm x 3.00mm x 0.60mm 4.90mm x 6.00mm x 1.00mm Features - Guaranteed long time supply availability for Industrial Applications. - No need for an optocoupler or a transformer tertiary winding. The output voltage can be set by two external resistors and the transformer turns ratio. - Uses Original Adapted Type ON-Time Control Technology. High-speed load response is realized and external phase pensation parts are unnecessary. - Fixed switching frequency and low output ripple - Highly efficient light load mode available (PFM operation) - Shutdown / Enable Control - Built-in N-Channel MOSFET - Soft start function - Output load pensation...
