High voltage (HV) bucks are widely used to power smart home IoT devices, home appliances, auxiliary power for industrial power, and E-meters. They are simple in design, low cost and require very little board space. Many electronic products use Bluetooth® Low Energy (LE) to exchange data through PCs, smartphones, as well as dedicated Bluetooth LE gateways. Bluetooth Low Energy has become one of the most popular standards for IoT applications. Renesas created a smart switching application by combining our HV buck and RX23W 32-bit microcontroller (MCU). This reference design shows a simple and effective design for a wall switch for smart appliances.
