Rohm Semiconductor has recently announced the availability of isolated flyback-type DC/DC converter control ICs for inverters in high power industrial equipment such as FA/solar inverters and power storage systems.
Isolation is almost always built into electronic equipment to provide protection against shock and damage. High voltage, high power industrial applications (including power storage systems and solar inverters which are seeing increased adoption) are no exception, requiring even more stringent reliability demands due to the harsher temperature conditions and the need for continuous, long-term operation.
Conventional solutions utilize a photocoupler and other components for flyback-type isolated power supply control. However, this presents challenges associated with current consumption and reliability (including circuit scale and product life). In contrast, the BD7F series reduces the number of external parts by nearly half by eliminating the need for a photocoupler, providing greater energy savings, reliability, and miniaturization.
