Product Overview
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.
