PLD08 DC-DC Series Data Sheet
Non-Isolated Converters
supplied by an isolated secondary source providing a
SELV also.
Thermal Considerations
The PLD08 Series converters are designed for natural
or forced convection cooling. The output power of the
converters is determined by the maximum semi-
conductor junction temperature.
To provide reliable
long-term operation of the converters, Power-One limits
maximum allowable junction temperature to 120 °C.
The graph in Figure 8 shows the maximum output
current of the PLD08 Series converter at different local
ambient temperatures at both natural and forced
(longitudinal airflow direction, from pin 3 to pin 1)
convection.
