46W, TRIPLE OUTPUT DC/DC CONVERTER
Power Good Operation
Local power is measured by several circuits shared with the overtemperature
system. The Pwr_LED_Drive Output is indirectly controlled by the on-board
microcontroller. The on-board PWM switching controller measures +3.3V and
+5V output voltages and all output currents. The microcontroller measures
input voltage and the +12V output voltage. The system requires that the
input voltage is within normal tolerances at all times. If the input voltage is
too high very briefly at startup (but not exceeding the absolute input voltage),
the system will start normally if the input voltage reaches acceptable limits
quickly (under half a second). This typically occurs as a load is applied.
When the system first starts, the Power Good LED (if installed) remains dark
briefly until all on-board startup conditions are met (less than half a second)
at which point the LED is illuminated. Operation proceeds as follows:
If the outputs on any lines deviate from approximately ±7% of nominal
and/or the output current is excessive, the outputs are all shut down and
the Pwr_LED_Drive Output is desasserted (LO, lamp dark). The system will
attempt to restart in about half a second by briefly turning on all outputs. If
successful and the fault is eliminated, the Pwr_LED_Drive Output will be
asserted (HI, lamp lit) and operation continues.
If the fault condition remains, the system will attempt to restart two more
times, spaced about half a second apart. If the fault remains for the third
time, the system will shut down and will not retest the fault. The system must
now be restored by fully cycling the input power.
The 3-fault countdown only occurs if the fault does not recover continuously
throughout the attempted restart interval. An occasional random shutdown
and successful restart will not trigger the 3-fault counter. However, external
logic should record the frequency and quantity of such shutdowns.
RoHS-5 compliance refers to the exclusion of the six hazardous substances
in the RoHS specification with the excepion of lead. C&D Technologies'
RoHS-5 products use all the conforming RoHS materials, however our
solders are Sn63/Pb37.
