功能:
- 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)
