FA5605N Key Features
- Voltage mode control
- Systems organized by circuit methods FA5604N: Applied to forward power supplies (maximum duty cycle = 46%) FA5605N/FA560
- Automatically reduces the switching frequency to suppress loss in stand-by mode
- The switching frequency can be set (RT pin)
- A drive circuit for connecting a power MOSFET directly
- Output peak current: +1.0A / -0.5A
- Overcurrent of primary side limiting function (IS pin negative voltage sense)
- Overload protection function (switching frequency control by VF pin)
- Overload protection function (CS pin)
- Built-in output overvoltage latch protection (stopping the latch by pulling up the CS terminal by external signals)
