INDUCTION COOKTOP

Description

The Induction cooktop solution is based on the iW248 IC. It offers pre‑programmable coil power, allowing users to effortlessly customize cooking modes. By integrating virtually all discrete components typically required for driving and protecting IGBTs, along with an optimized state‑machine digital core that replaces a traditional microcontroller, the iW248 significantly reduces solution size and eliminates up to 35 external components.

The iW248 also features a proprietary low‑power continuous operating mode that enables smooth performance at low power levels, with precise control in 10‑W increments, supporting induction cooktop applications up to 2100 W.

Features

• Customizable timer function and power setting
