Short Circuit Condition
When a converter is in current-limit mode, the output voltage will drop as
the output current demand increases. If the output voltage drops too low,
the magnetically coupled voltage used to develop primary side voltages
will also drop, thereby shutting down the PWM controller. Following a
time-out period, the PWM will restart causing the output voltages to begin
ramping to their appropriate values. If the short-circuit condition persists,
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 UHE is capable of enduring an indefinite short circuit output condition.
FEATURES AND OPTIONS
On/Off Control
The input-side, remote On/Off Control function (pin 4) can be ordered to
operate with either polarity:
Standard models are equipped with Positive-polarity (no part-number
suffix) and these devices are enabled when pin 4 is left open (or is pulled
high, applying +3V to +V
Positive-polarity devices are disabled when pin 4 is pulled low (0 to 0.8V
with respect to –Input).
Optional Negative-polarity devices ("N" suffix) are off when pin 4 is left
open (or pulled high, applying +3.5V to +V
low (0 to 0.8V) with respect to –V
Dynamic control of the remote on/off function is best accomplished with a
mechanical relay or an open-collector/open-drain drive circuit (optically
isolated if appropriate). The drive circuit should be able to sink appropriate
current (see Performance Specs) when activated and withstand appropriate
voltage when deactivated. Applying an external voltage to pin 4 when no
input power is applied to the converter can cause permanent damage to
the converter.

Trimming Output Voltage
UHE converters have a trim capability (pin 9) that allows users to adjust
the output voltages ±5% of V
output voltages can be accomplished via a trim pot (Figure 6) or a single
fixed resistor as shown in Figures 7 and 8. A single fixed resistor can
increase or decrease the output voltage depending on its connection. The
resistor should be located close to the converter and have a TCR less than
00ppm/°C to minimize sensitivity to changes in temperature. If the trim
function is not used, leave the trim pin floating.
A single resistor connected from the Trim (pin 9) to the +Output (pin 6), or
+Sense where applicable, will decrease the output voltage for all models
with the exception of the .2V models, which will increase the output
voltage in this configuration. A resistor connected from the Trim (pin 9) to
the –Output (pin 7), or –Sense where applicable, will increase the output
voltage for all models with the exception of the .2V models, which will
decrease the output voltage in this configuration.
Trim adjustments greater than the specified ±5% can have an adverse
affect on the converter's performance and are not recommended. Exces-
sive voltage differences between V
adjustment of the output voltage, can cause the overvoltage protection
circuitry to activate (see Performance Specifications for overvoltage limits).
Power derating is based on maximum output current and voltage at the
converter's output pins. Use of trim and sense functions can cause output
voltages to increase, thereby increasing output power beyond the con-
verter's specified rating or cause output voltages to climb into the output
overvoltage region. Therefore:
