Two new series of very high isolation DC/DC’s designed for use in high speed gate drive circuits. The MIG200lhi (for igbt circuits) and MSC200lhi (for sic circuits) feature an i/o isolation of 5kv and an electrical clearance/creepage distance of 14.74 mm. For most devices now on the market, the i/o isolation is 3kv and the creepage distance is about 8 mm. The wider gap allows these units to maintain a continuous barrier withstand voltage of 1,700v even when the unit is damaged.
The MIG200lhi series consists of three models with inputs of 12, 15 or 24 vdc and outputs of +15v/-9v. The MSC200lhi series has six models with inputs of 12, 15 or 24 vdc and outputs of +15v/-4v or +20v/-5v. Standard features for all models include 5,000 vac i/o isolation (reinforced), continuous short circuit protection, up to 87% efficiency, and a low isolation capacitance of only 3.5 pf. The mtbf (per mil hdbk 217f) is greater than 3.5 mhours. All models are approved to en 62368 (ul).
