Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, has unveiled a family of new 700V buck regulators that offers designers several advantages.
The new RAA2230XX devices deliver superior power consumption, noise and EMI suppression, as well as reduced overall system cost. They’re ideal for a wide range of applications, including home appliances, sensing systems (such as smoke alarms and gas sensors), white goods, power meters, and industrial controls.
The RAA2230XX buck regulators consume only 10 to 30mW when idle, helping system designers meet ever-tightening standby power regulations. They feature a unique switching algorithm that minimizes electromagnetic interference (EMI) and eliminates audible noise, such as humming or whining that can affect competitors’ solutions.
The new regulators also can supply as low as 3.3V output, enabling designers to eliminate a second-stage, low, dropout regulator (LDO), saving BOM cost and board space.
These buck regulators connect to the AC line to power Renesas MCUs, sensors, and other digital ICs.
“The RAA2230XX family is a superior solution that complements our deep and broad line of products for the home and industrial markets,” saidPhilip Chesley, VP of the Industrial and Communications Business Division at Renesas. “This is an excellent example of Renesas’ ability to combine great products with design and applications expertise to help our customers get to market faster with differentiated end products.”
