InnoSwitch5-Pro: Compact and Efficient Power Solutions

The InnoSwitch5-Pro series from Power Integrations offers a highly integrated solution for power supply design, combining a robust 750 V or 900 V PowiGaN primary switch with digital programmability via an I²C interface. These ICs achieve zero-voltage switching (ZVS) without requiring additional high-voltage switches, resulting in over 95% efficiency and eliminating the need for heatsinks. This makes them ideal for creating ultra-compact adapters up to 220 W.

Engineers can benefit from the reduced component count and PCB area, simplifying the development of efficient, programmable power supplies. The InnoSwitch5-Pro supports a wide range of fast-charging protocols, including USB PD, PPS, and UFCS, ensuring compliance with global standards. The high switching frequency and GaN technology minimize switching losses, enabling the creation of compact and efficient power adapters.
