Electrical Characteristics

Tj = 25°C unless otherwise specified.

The

• denotes specifications which apply over the specified operating temperature range.

Notes:

1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are

measured at a constant junction temperature by low duty cycle pulse testing.

2. Line and load regulation are guaranteed up to the maximum power dissipation (18W). Power dissipation is determined by

input/output differential and the output currrent. Guaranteed maximum output power will not be available over the full input/

output voltage range.
