Notes:

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

3. When measuring output ripple & noise, it is recommended that an external capacitor (4.7 µF typ.) be

dual output models.

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 recommended 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 recom-

mended; 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 MHI1500x-xxB series is a good choice

for applications involving high speed switch-

ing, 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 correspondingly low capacitive

coupling rates) allow them to be safely used

in applications with highly dynamic switched

AC or DC.
