Specifications

Notes to Specifications

1.

Tested at each output.

2.

Parameter guaranteed by line and load regulation tests.

3.

At least 20 percent of the total output power should be taken from the (+5V) main output.

4.

Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz.

5.

An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit

protection and is the condition of maximum power dissipation.

6.

Above 125

°C case temperature, derate output power linearly to 0 at 135°C case
