However, it has been designed specifically to power 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 IG120-15 input) are: 1. The IG100 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 IG100 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 chart on page 2. 3. The addition of the input filter components (C1 and LDM) will typically bring the circuit within the limits of EN 55022 Class B. The recom- mended values for these components are shown in the table at right. If meeting EN 55022 class B is not a concern, the inductor (LDM) can be eliminated (as shown in the circuit diagram below). In this case, the recommended value for C1 is 100 µF/35V. 4. The recommended values for the output filter capacitors C2 and C3 are shown in the table at right. 5. C1, C2 and C3 should be mounted as close to the unit as possible. To ensure peak gate current, these capacitors should have a low ESR. The trace (or wire) between the DC/DC and the driver circuit should be as short as possible. 6. The average output power of the driver circuit must be lower than output power of the DC/DC. Derating Curve 7.
