Output voltage accuracy is measured with an output load of 100 mA. The output accuracy over the output load range of 10% to 100% is given in the graphs below. 2. Load regulation is measured from 10% load to full load. 3. When measuring output ripple & noise, it is recommended that an external capacitor (1 µF to 10 µF) be placed from each output to common. 4. Operation at no-load will not damage these units. However, they may not meet all specifi cations. 5. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above for the correct rating. The IG275E series is designed to operate with the IGD962 IGBT driver.

However, with asymmetrical outputs, an isolation barrier specifi ed at 3 kVAC, very low isolation capacitance and a wide operating temperature range; they are an ideal choice for IGBT drive & control circuits. They are specifi cally designed for use with 962 type IGBT drivers. A typical connection to the MicroPower Direct IGD962 is shown in the diagram above. Some notes on this circuit (starting with the IG275-24E input) are: 1. The IG275-24E DC/DC should be mounted as close to the IGBT driver as possible, to minimize the length of connecting board traces or wires. 2. The IG275E series does not include overload protection (typical of most low power DC/DC’s). It is recommended that an external fuse be used. The recommended fuse is shown in the model selection chart on page 2. 3. The addition of the input fi lter components (C 4, C5 and LDM) will typically bring the circuit to within the limits of EN 55022 Class B. Capacitor C Y is only required on model IG275-24E. The recom- mended values for these components are shown in the table below. If meeting EN 55022 class B is not a concern, the inductor (LDM) and capacitor C4 can be eliminated (and CY for the IG275-24E). In this case, the recommended value for C5 is 100 µF/35V. 4. The recommended values for the decoupling capacitors C6 and C7 are shown in the table below. These low ESR capacitors should be mounted as close to the IGD962 driver as possible. 5. Input fi ltering components (C4, C5 and LDM) should be mounted as close to the unit as possible. The trace (or wire) between the DC/DC and the driver circuit should be as short as possible. 6. The µC of the IGBT module should be 2 or less. For IGBT modules with a µC greater than 2, we recommend our IG480 series. 7. Recommended values for components are: Component 12 VIN 15 VIN 24 VIN C4, C5 4.7 µF/50V 4.7 µ F/50V 4.7 µ F/50V LDM 6.8 µ H 6.8 µ H 6.8 µ H CY --- --- 1 nF/3 kV C6 100 µF/35V 100 µ F/35V 100 µ F/35V C7 100 µF/35V 100 µ F/35V 100 µ F/35V The IG275E series is a good match for the IGD962 type IGBT driver. When combined, the IGD962 & IG275E provide the isolated gate drive required for controlling high power IGBT modules. The IGD962 features an internal high speed optocoupler, high transient immunity, short circuit protection and a fault signal output. It is packaged in a compact single-in-line (SIP) package that minimizes the required printed circuit board space. The IGD962-5A converts logic level control signals into a fully isolated gate drive of +15V/-8.5V. Gate drive current is 5A peak. Gate drive power isolation is provided by the IG275E series DC/DC converters (see connection diagram above with the IG275-24E). Control signal isolation is provided by an internal high speed optocoupler. Desatura- tion detection is used for short circuit protection. See the IGD962-5A datasheet (available on our website) for more information on the driver specifications and connection.
