Beschreibung

BD7F100HFN-LB is an optocoupler-less
Isolated Flyback Converter. An optocoupler or a
3rd winding from a transformer needed in the
conventional application of feedback circuits
becomes unnecessary to obtain a stable output
voltage isolated by the transformer. The number
of parts is reduced drastically producing a smallsized
and high-reliability application isolated
type 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

Merkmale

  • 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 O
