PT4850 Series
25-A Triple Output Isolated DC/DC
Converter For Logic Applications
Efficiency vs Output Load
PT4851 Performance Characteristics
(See Note A)
(Io1 =10A, Io2 =7.5A, Io3 =7.5A represents 100% Load)
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:
SOA curves represent operating conditions at which the internal components are at or below the manufacturer’s maximum rated operating temperatures.
Power Dissipation vs Output Load
PT4851 Safe operating Area Curves (See Note B)
(Io1 + Io2 + Io3 =25A, represents 100% load)
