PT4822—48V
35-W Triple Output Isolated DC/DC
Converter for Logic Applications
PT4822 Performance Characteristics
(See Note A, B)
Typical Characteristics
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.
PT4822 Thermal Performance (See Note C)
(Io1 + Io2 + Io3 =12A, represents 100% Load)
