ATO28XXT Series

CASE = -55°C to +105°C, VIN = +28V ± 5% unless otherwise specified

Specifications

Tested at each output.

Parameter guaranteed by line and load regulation tests.

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

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

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.

Above 105

°C case temperature, derate output power linearly to 0 at 125°C case
