Renesas Electronics launches new 700V step-down regulator product family

Suitable for applications such as home appliances, smart homes, sensing systems, electricity meters, and industrial control

The new product has extremely low power consumption, excellent EMI performance, and no audio noise, which can reduce BOM costs and better match Renesas MCU and sensor product lines

On June 24, 2021, Renesas Electronics Group (TSE: 6723), a global semiconductor solution provider, announced the launch of a new 700V step-down regulator product family-RAA2230XX series products, which will provide designers with more Competitive solutions have more advantages. This new product has excellent low power consumption, low noise, and electromagnetic interference (EMI) suppression capabilities, and has a great system cost advantage. It has become home appliances, sensing systems (such as smoke alarms and gas sensors), white goods, electricity meters, and Ideal for various applications such as industrial control.

The new RAA2230XX buck regulator has a power consumption of only 10mW to 30mW at no load, which can help system designers meet increasingly stringent requirements for low standby power consumption. They use a unique switching algorithm to minimize electromagnetic interference and eliminate audio noises such as hum or whine that are common in similar solutions in the market. The new regulator can also provide an output as low as 3.3V, so that designers do not need a second-stage low-dropout regulator (LDO), thereby saving BOM cost and board space.

The new step-down regulator is powered by AC, and after step-down, it powers Renesas' MCU, sensors, and other digital ICs. At the same time, Renesas has developed a number of "successful product portfolios" that include this new product, consisting of complementary analog, power, clock, and embedded processing products, creating an easy-to-use architecture that simplifies the design process and Significantly reduce customer design risks for various applications. For example, "Home Smoke Detector" successfully demonstrated a turnkey solution for residential smoke alarms suitable for intelligent industrial control terminals. In addition, Renesas offers more than 200 successful product portfolios that seamlessly work with compatible devices.

Philip Chesley, Vice President of Renesas Electronics Industry and Communications Division, said: "The outstanding new RAA2230XX series products expand our strong and rich product line for the home and industrial markets. This product is also Renesas’s professional design and application of excellent products. An excellent example of the integration of knowledge can help our customers get to market faster with differentiated end products."
