The specified maximum capacitive load is for each output. 2. Load regulation is measured over a range of 25% IOUT to 100% IOUT. 3. When measuring output ripple & noise, it is recommended that an external capacitor (0.47 µF typ.) be placed from the +VOUT to the -VOUT pins for single output units and from each output to common for dual output models. To further reduce 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. A 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 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. 600 90.0 77 1,000 1,000 Derating Curve IGBT Applications Notes: The MHI300x-xxARU 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 correspondingly low capacitive coupling rates) allow them to be safely used in applications with highly dynamic switched AC or DC.
