NOTES:
1. di/dt=0.1A/1uS, Vin= nominal line,Tc=25°C; load change
=0.5 Io max. to 0.75 Io max. and 0.75 Io max. to 0.5 Io
max.
2. Measured with 1uF ceramic cap. Connected to the output
pins.
3. Measured from low line to high line.
4. Measured from full load to 1/10 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.
