Induction Heating Rice Cooker

Overview

This induction heating (IH) rice cooker design features a heating block and human machine interface (HMI). A highly integrated smart power controller ensures efficient and high-performance IH operation, ensuring precise temperature control and reliable cooking results.

System Benefits​:

  • Simplified and high-performance design leverages a smart power controller for efficient heating management.
  • A single compact MCU supports HMI and touch key display.
  • A high-performance buck regulator provides ultra-low standby power and up to 2.5W output power.
