This DC-DC converter module uses 2nd Generation power processing, control and packaging technologies to provide the performance,
flexibility and cost effectiveness expected of a mature power component.
For example, a plated-cavity core transformer couples widely separated primary and secondary windings,
resulting in low in-to out parasitic capacitance and noise. High frequency ZCS/ZVS switching, advanced power semiconductor packaging
and thermal management provide high power density with low temperature gradients.
Extensive use of silicon integration results in 1/3 the part count of a 1st Generation converter.
The module contains “watchdog” circuitry which monitors input voltage, operating temperature and internal operating parameters.
In the event that any of these parameters are outside of their allowable operating range, the module will shut down and PC will go low.
PC will periodically go high and the module will check to see if the fault (as an example, overtemperature) has cleared.
If the fault has not been cleared, PC will go low again and the cycle will restart. The SC pin will go low in the event of a fault
and return to its normal state after the fault has been cleared. See Figures 2 and 4.
