Model Selection Guide

Mechanical Dimensions

Notes:

1. Load regulation is measured for an output change of 20% to 100%.

2. When measuring output ripple, it is recommended that an external 0.33 µF ce-

ramic capacitor be placed from the +Vout pin to the -Vout pin. For noise sensitive

applications, the use of 3.3 µF capacitors will reduce the output ripple.

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

specifications.

4. 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 appli-

cations 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 (ESR <1.0

 at 100 kHz) capacitor

be mounted close to the converter. For 5V input units a 2.2 µF is recommended; a

1.0 µF for 12V & 15V input units; and for 24V input models, a 0.47 µF.

5. 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.
