Simple DC/DC - ICs for Microcontroller Power Supply System

"Simple DC/DC" - Suitable for Renesas Microcontroller and SoC

We are involved in Renesas microcontroller and SoC power design with many customers on-site, where we can get feedback and opinions directly from the source. This product is the result of consolidating those feedback and opinions to enable us to offer a simple design experience for Renesas microcontrollers and SoCs to as many of our customers as possible.

Reduce design time for power supply of MCU and SoC
Provide schematic connection with our microprocessor and SoC, suggested parts, etc. Shortened development period of the system with "Easy design".
Simple & compact design
Built-in main circuit of power supply cirucuit. Number of components in the power supply, mounting area significantly reduce.

 

Reduce power consumption effortlessly
Built-in low consumption mode, AutoPFM mode. According to the operation mode of microcomputer, to realize overall system power consumption.
