Renesas Electronics Launches New 700V Step-Down Regulator Family

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

New products feature extremely low power consumption, excellent EMI performance and no audible noise, reducing BOM costs and better matching Renesas MCU and sensor product lines

Tokyo, Japan, June 24, 2021 - Renesas Electronics Corporation, a global supplier of semiconductor solutions, today announced the launch of a new 700V step-down regulator product family, the RAA2230XX series, which brings designers more advantages than other competing solutions. The new product has excellent low power consumption, low noise and electromagnetic interference (EMI) suppression capabilities, and has great system cost advantages, making it an ideal choice for various applications such as home appliances, sensing systems (such as smoke alarms and gas sensors), white goods, electricity meters, and industrial controls.

The new RAA2230XX step-down regulators consume only 10mW to 30mW when not loaded, helping system designers meet increasingly stringent low standby power requirements. Through a unique switching algorithm, they minimize electromagnetic interference and eliminate audio noise such as hum or whine that is common in similar solutions on the market. The new regulators can also provide outputs as low as 3.3V, allowing designers to eliminate the need for a second-stage low-dropout regulator (LDO), saving BOM cost and board space.

The new buck regulator is powered by AC and steps down the voltage to power Renesas' MCU, sensors, and other digital ICs. At the same time, Renesas has developed a number of "successful product combinations" including this new product, which are composed of complementary analog, power, clock, and embedded processing products to create an easy-to-use architecture that simplifies the design process and significantly reduces customers' design risks for various applications. For example, the "Home Smoke Detector" successfully demonstrated a turnkey solution for residential smoke alarms suitable for smart industrial control terminals.

“The new RAA2230XX Series expands our strong and extensive product line for the home and industrial markets with our outstanding products,” said Philip Chesley, Vice President of Industrial and Communications Business Division at Renesas Electronics. “It is also an excellent example of how Renesas combines product excellence with design and application expertise to help our customers get to market faster with differentiated end products.”

Key Features of the RAA2230XX Buck Regulator

Supports non-isolated buck and isolated flyback topologies, allowing customers to develop multiple types of AC input power supplies

Ultra - low 10mW to 30mW no-load power consumption to meet stringent standby power requirements

Ultra - low EMI and no audio noise, avoiding later product development problems

 Available in TSOT23-5, SOIC-8 and SOIC-7 packages, pin-compatible with competing products for easy replacement

Availability

The new 700V RAA2230XX step-down regulators are available now; the series includes 2W, 4W, and 8W versions. Renesas also offers a variety of evaluation boards for different package and output combinations.
