INDUCTION COOKTOP

Description

The Induction Cooktop solution is based on the IC iW248 . It offers pre-programmable coil power which allows users to customize the cooking modes effortlessly. Integrating virtually all discrete components normally used to drive and protect IGBTs, plus an optimized state machine digital core that replaces a traditional microcontroller, the iW248 significantly reduces solution size and eliminates up to 35 components. 

The iW248 also features a proprietary low-power continuous mode that allows for smooth operation at low power states and control in 10W increments for induction cooktop applications up to 2100W.

Features

• Customizable timer function and power setting
• Integrated IGBT controller: valley-mode switching control
