Notes:
1. The maximum output power can be limited by junction temperature.
2. 230 VAC or 100/115 VAC with doublers.
3. Typical continuous power in a non-ventilated enclosed adapter with sufficient drain pattern as a heat sink,
at TA=50°C ambient.
4. Maximum practical continuous power in an open-frame design with sufficient drain pattern as a heat sink,
at TA=50°C ambient.
