B: for the other models
2. Measured with 0.1uF ceramic cap. Connected to the
output pins.
3. Measured from low line to high line.
4. Measured from full load to 1/4 full load.
5. The converter required a minimum 10% loading on the
output. Operation below 10% load conditions will not
damage these devices. However they may not meet all
listed spec.
6. Maximum case temperature under any operating
condition should not be exceed 100°C.
7. Metal case only.
