Output Voltage Adustment
The output voltage may be adjusted over a limited range by connecting an
external trim resistor (Rtrim) between the Trim pin and Ground. The Rtrim
resistor must be a 1/10 Watt precision metal fi lm type, ±0.5% accuracy or
better with low temperature coeffi cient, ±100 ppm/
resistor close to the converter with very short leads or use a surface mount
trim resistor.
specifi ed limits of the output voltage or the converter’s maximum power
rating when applying these resistors. Also, avoid high noise at the Trim
input. However, to prevent instability, you should never connect any capaci-
tors to Trim.

Input Fusing
Certain applications and/or safety agencies may require fuses at the inputs
of power conversion components. Fuses should also be used when there
is the possibility of sustained input voltage reversal which is not current-
limited. For greatest safety, we recommend a fast blow fuse installed in the
ungrounded input supply line.
For safety agency approvals, install the converter in compliance with the
end-user safety standard.

Input Under-Voltage Shutdown and Start-Up Threshold
Under normal start-up conditions, converters will not begin to regulate
properly until the rising input voltage exceeds and remains at the Start-Up
Threshold Voltage (see Specifi cations). Once operating, converters will not
turn off until the input voltage drops below the Under-Voltage Shutdown
Limit. Subsequent restart will not occur until the input voltage rises again
above the Start-Up Threshold. This built-in hysteresis prevents any unstable
on/off operation at a single input voltage.
Shutdown whose voltage decays as input current is consumed (such as
capacitor inputs), the converter shuts off and then restarts as the external
capacitor recharges. Such situations could oscillate. To prevent this, make
sure the operating input voltage is well above the UV Shutdown voltage AT
ALL TIMES.
Start-Up Delay
Assuming that the output current is set at the rated maximum, the Vin to
Vout Start-Up Delay (see Specifi cations) is the time interval between the
point when the rising input voltage crosses the Start-Up Threshold and the
fully loaded regulated output voltage enters and remains within its specifi ed
regulation band. Actual measured times will vary with input source imped-
ance, external input capacitance, input voltage slew rate and fi nal value of
the input voltage as it appears at the converter.
the PWM controller at power up, thereby limiting the input inrush current.
assumes that the converter already has its input voltage stabilized above
the Start-Up Threshold before the On command. The interval is measured
from the On command until the output enters and remains within its
specifi ed accuracy band. The specifi cation assumes that the output is fully
loaded at maximum rated current.
Recommended Input Filtering
The user must assure that the input source has low AC impedance to
provide dynamic stability and that the input supply has little or no inductive
content, including long distributed wiring to a remote power supply. The
converter will operate with no additional external capacitance if these
conditions are met.
Users should be aware however of input sources near the Under-Voltage
