Model Selection Guide
Notes:
1. When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor
2. Transient recovery is measured to within a 1% error band for a load step change of 75% to
3. The maximum control current at the on/off pin (pin 3) during a logic high is 5 µA. The maximum
4. Operation at no-load will not damage these units. However, they may not meet all specifi ca-
5. The converter should be connected to a low ac-impedance source. An input source with a
6. It is recommended that a fuse be used on the input of a power supply for protection. See
External Trim
For continuous UP/Down trimming capability, connect a 10 kW poten-
tiometer between the plus and minus outputs with the wiper arm con-
nected to the V
An external resistor may also be used to adjust the converter output.
To adjust the output UP, connect a 5%, 3W resistor between the minus
output pin and the Vout trim pin. The output voltage is increased per
the equation:
To adjust the output DOWN, connect a 5%, 3W resistor between the
plus output pin and the V

control current to the on/off pin at logic low is -100 µA. If the on/off pin is left open, the unit operates.
If it is grounded, the unit will shut off.
tions.
highly inductive impedance may affect the stability of the converter. In applications where
the converter output loading is high and input power is supplied over long lines, it may be
necessary to use a capacitor (such as a low ESR 10.0 µF) on the input to insure start-up.
