Notes:

1. The specified maximum capacitive load is for each output.

3. When measuring output ripple & noise, it is recommended that an external capacitor (0.47 µF typ.) be placed from the

output ripple, a 3.3 µF is recommended.

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

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 recom-

mended that a low ESR (ESR <1.0

at 100 kHz) capacitor be mounted close to the converter. For 12V input units a

10 µF is recommended; for 12V input units, a 4.7 µF; and for 24V units a 2.2 µF.

6. Operation at no-load will not damage the unit, but they may not meet all specifications.

7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection tables for

the correct rating.

IGBT Applications

Notes:

The MHI1000x-xxB series is a good

choice for applications involving high

speed switching, such as driving IGBTs.

They are designed to withstand the

extra stress caused by the high voltage

switching transients present in IGBT

drive circuits.

All of the MHIxxx series have isolation

levels that range from 5.2 to 8 kV. Many

of these have reinforced insulation. The

high isolation levels (and the correspond-

ingly low capacitive coupling rates) allow

them to be safely used in applications

with highly dynamic switched AC or DC.
