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) |
