Line regulation is measured for an input voltage change of ±10%. 2. Load regulation is measured from 10% load to full load. 3. When measuring output ripple & noise, it is recommended that an exter- nal capacitor (1 µF to 10 µF) be placed from each output to common. The typical noise specifi ed for the IG220-12 is 100 mV P - P . 4. The unit will meet the radiated and conducted EMI specifi cations with the addition of external components as shown in the con- nection diagram on page 3. 5. Operation at no-load will not damage these units. However, they may not meet all specifi cations. 6. It is recommended that a fuse be used on the input of a power supply for protection.

With asymmetrical outputs of +20 VDC & -4 VDC, an isolation barrier specifi ed at 3.5 kVAC, very low isolation capaci- tance and a wide operating temperature range; they are an ideal choice for Silicon Carbide (SiC) MOSFET drive & control circuits. SiC MOSFETs are often used in high voltage, very high fr equency applications. The figure above illustrates a typical connection to a driver circuit. Again, MPD offers a number of power products that can be used in gate driver circuits (IGBT and SiC). The circuit above uses three MPD parts. At the top, a DC/DC converter is used convert the 24 VDC bus into voltage levels required by the driver components (if required). This converter also iso- lates the driver circuit from the power bus. MPD offers hundreds of standard DC/DC converters that can be used for this purpose. The MSR7805-05WUP is a miniature, very low cost switching regulator. In this circuit, it con- verts the 24 VDC bus into a regulated 5 VDC that is used for the input signal pull-up. 7. Recommended values for components are: Component 12 VIN 15 VIN 24 VIN C4 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 C5 4.7 µF/50V 4.7 µ F/50V 4.7 µ F/50V 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 IG220-24 converts the input 24 VDC into asymmetrical +20 VDC & -4 VDC outputs. These outputs are used to set up the positive/minus gate bias required for high and low side switching. The IG220-24 also provides power isolation for the gate drive. All models are specifi ed for 3.5 kVAC I/O isolation. The optocoupler provides isolation for the control signal. Some notes on the IG220-xx connection (starting with the input) ar 1. The IG220-xx DC/DC should be mounted as close to the SiC driver as possible, to minimize the length of connecting board traces or wires. 2. The IG220 series does not include overload pro- tection (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 chart on page two. 3. The addition of the input fi lter components (C C5 and LDM) will typically bring the IG220-xx cir- cuit to within the limits of EN 55022 Class B. The recommended values for these components are shown in the table at right. If meeting EN 55022 class A or B is not a con- cern, the inductor (LDM) and one capacitor (C can be eliminated. 4. The recommended values for the decoupling capacitors C6 and C 7 are shown in the table below. These low ESR capacitors should be mounted as close to the driver circuit as pos- sible. 5. Input fi ltering components (C 4, C5 and LDM) should be mounted as close to the unit as pos- sible. The PC board trace (or wire) between the DC/DC and the driver circuit should be as short as possible. 6. The use of tantalum capacitors in this circuit should be avoided.
