In order to develop on-chip transformer processes, Rohm utilized its proprietary microfabrication expertise. The unique design reduces the size to a compact SSOP-B20W package while eliminating the need for external parts, cutting the mounting area by approximately 50% compared to conventional products. Moreover, the original core-less transformer technology integrates an isolation function ensuring an isolation voltage of 2,500 Vrms.

In addition, multiple protection functions such as thermal shut-down and short circuit protection supporting desat function , fault and load control are included for high reliability, decreasing design effort while further contributing to miniaturization. A soft turn-off function deactivates the inverter in case of desaturation.
