Notes:
1. The maximum specification indicates the converter’s total output power, Up
to 75% of the total is available from either output providing the other output
maintains a minimum of 25% of the total power.
3. Time to settle within 1% of V
OUT
4. Transition ≥ 10 µs.
2. Short circuit is measured with a 50 mohm resistive load.
