Note:
1. All specifications are measured at TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.
2. The CTRL control pin voltage is referenced to GND.
3. Typical
efficiency
value at nominal input voltage and full load.
4. Capacitor MAX load tested at nominal input voltage and constant resistive load.
5. Refer to the diagram of Output Voltage trim up/down for trim applications.
6. The products cannot be used in parallel and in plug and play.
