Notes:
1. When measuring output ripple, it is recommended that an external 4.7 µF ceramic capacitor
be placed from the +Vout pin to the -Vout pin for single output units and from each output to
common for dual output units.
2. These converters are specified for operation without external components. However, in some
applications the addition of input/ouput capacitors will enhance stability and reduce output
ripple. Recommended capacitor values are 100
µF
for C
IN
and 100 - 220
µF
for C
OUT
.
3. Transient recovery is measured to within a 1% error band for a load step change of 75% to
100%.
4. The maximum control current at the on/off pin (pin 6) during a logic high is 50
µA.
The maximum
control current to the on/off pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off pin is left open,
the unit operates. If it is grounded, the unit will shut off.
5. Operation at no-load will not damage these units. However, they may not meet all specifications.
6. Dual output units may be connected to provide a 10 VDC, 24 VDC or 30 VDC output. To do this,
connect the load across the positive (+Vout) and negative (-Vout) outputs and float the output
common.
7. It is recommended that a fuse be used on the input of a power supply for protection. See the
table above for the correct rating.

Remote ON/OFF Notes:
1. Maximum sink current at the on/off pin (pin 6) during a logic
low is 100
µA.
2. Maximum allowable leakage current of a switch connected to
the on/off terminal (Pin 6) at logic high (2.5V to 100V) is 5
µA.
Mechanical Dimensions
External Trim
A simple external circuit may be used to
adjust the converter output (single output
models only). To adjust the output DOWN,
connect a 5%, 3W resistor between the
plus output pin and the Vout trim pin. To
adjust the output UP, connect a 5%, 3W
resistor between the minus utput pin and
the Vout trim pin.
For UP/Down trimming capability, connect
a 10 kW potentiometer between the plus
and minus outputs with the wiper arm
connected to the Vout trim pin.
The trim range is
±10%.
