NOTE
- Ripple and noise are measured at 20 MHz bandwidth using a 12-inch twisted-pair wire terminated with a 0.1 µF and 47 µF parallel capacitor.
- Line regulation is measured from low line to high line at rated load.
- Load regulation is measured from 0% to 100% rated load.
- Unless otherwise specified, all parameters are measured at nominal input voltage, rated load, and 25 °C ambient temperature.
- Derating may be required under low input voltage conditions. Refer to the Static Characteristics section for details.
- The power supply is considered a component used in the final equipment. Therefore, EMC performance may be affected by the complete installation, and the final equipment manufacturer must re-qualify EMC compliance for the complete system.
