Short Circuit Condition
When a converter is in current limit mode the output voltages will drop as
the output current demand increases. If the output voltage drops too low, the
magnetically coupled primary side voltages will also drop, thereby shutting
down the PWM controller.
Following a time-out period, the PWM will restart, causing the output voltage
to begin ramping to its appropriate value. If the short-circuit condition per-
sists, another shutdown cycle will be initiated. This on/off cycling is referred
to as "hiccup" mode. The hiccup cycling reduces the average output current,
thereby preventing internal temperatures from rising to excessive levels. The
UEP is capable of enduring an indenite short circuit output condition.
Thermal Shutdown
These UEP converters are equipped with Thermal Shutdown Circuitry. If
environmental conditions cause the internal temperature of the DC/DC
converter rises above the designed operating temperature (typically 118°C
case), a precision temperature sensor will power down the unit. When
the internal temperature decreases below the threshold of the temperature
sensor the unit will self start. .
Output Overvoltage Protection
Output voltages are monitored for an overvoltage condition via magnetic
coupling to the primary side. If the output voltage should rise to a level
which could be damaging to the load circuitry, the sensing circuitry will
power down the PWM controller causing the output voltages to decrease.
Following a time-out period the PWM will restart, causing the output voltages
to ramp to their appropriate values. If the fault condition persists, and the
output voltage again climbs to excessive levels, the overvoltage circuitry
will initiate another shutdown cycle. This on/off cycling is referred to as
"hiccup" mode.
