PT4826 Performance Characteristics
(See Notes A, B)
Typical Characteristics
Power Dissipation vs Output Load
Note A:
All Characteristic data in the above graphs has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note B:
Output Load (%) represents the percent drawn from each output of the stated 100% load condition.
Note C:
SOA curves represent operating conditions at which the internal components are at or below the manufacturer’s maximum rated operating temperatures.
