Model Selection Guide

Mechanical Dimensions

Notes:

1. When measuring output ripple, it is recommended that an external 0.47 µF ceramic capacitor

dual output models. For noise sensitive applications, the use of 3.3 µF capacitors will reduce

the output ripple.

2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%.

3. The maximum control current at the on/off input (pin 1) during a logic high (+5V) is 500 µA.The maximum

control current to the on/off pin at logic low (0V) is -500 µA. If the on/off pin is left open, the unit operates.

If grounded, the unit will shut off.

4. Operation at no-load will not damage these units. However, they may not meet all specifications.

5. The converter should be connected to a low ac-impedance source. An input source with a

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 on the input to insure start-up.

In this case, it is recommended that a low ESR (<1.0

 at 100 kHz) capacitor be mounted

close to the converter. For 24V input units a 4.7 µF is recommended and for 48V input models,

a 2.2 µF.

6. 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.
