Description
This is a Vin=24V, three of Vout=15V, Iout=0.15A design.
Features
- 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)
Typical applications
- Industrial equipment Isolated Power Supply
