Beschreibung

BD7F100HFN-LB is an optocoupler-lessIsolated Flyback Converter. An optocoupler or a3rd winding from a transformer needed in theconventional application of feedback circuitsbecomes unnecessary to obtain a stable outputvoltage isolated by the transformer. The numberof parts is reduced drastically producing a smallsizedand high-reliability application isolatedtype power supply.- No need for an optocoupler or a transformer 3rd winding.- Adapted Type ON-Time Control Technology.- High-speed load response- Efficient light load mode- Enables Shutdown Control- Built-in N-Channel MOSFET- Soft start function- Output load compensation function- Complete protection functions UVLO, OCP, TSD

Eigenschaften

 Guaranteed long time supply availability forIndustrial Applications. No need for an optocoupler or a transformer tertiarywinding.The output voltage can be set by two externalresistors and the transformer turns ratio. Uses Original Adapted Type ON-Time ControlTechnology.High-speed load response is realized and externalphase compensation parts are unnecessary. Fixed switching frequency and low output ripple Highly efficient light load mode available (PFMoperation) Shutdown / Enable Control Built-in N-Channel MOSFET Soft start function Output load compensation function Protection functions:VIN Under Voltage Lock-Out (VIN UVLO)Over Current Protection (OCP)Thermal Shutdown Protection (TSD)

Typische Anwendungen

  • Industrial equipment Isolated Power Supply
