ROHM BD7F200HFN

Beschreibung

This product guarantees long time supply availability in the industrial instrumentation market.BD7F200 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 becomes 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 compensation parts become unnecessary, therefore a highly efficient isolated type power supply application can easily be produced.

Eigenschaften

• 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 compensation 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 compensation function
• Protection functions:
• VIN Under Voltage Lock-Out (VIN UVLO)
• Over Current Protection (OCP)
• Thermal Shutdown Protection (TSD)
