The RAA2230XX devices deliver improved power consumption, noise and EMI suppression, as well as reduced overall system cost. They are intended 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.
These devices consume 10mW to 30mW when idle, helping system designers meet ever-tightening standby power regulations. They also feature a unique switching algorithm which reduces electromagnetic interference (EMI) and eliminates audible noise, such as ‘humming’ or ‘whining’ that can affect some alternative solutions. The 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.
The buck regulators connect to the AC line to power Renesas MCUs, sensors and other digital ICs. Renesas has developed numerous 'Winning Combinations' that include the new devices.
Winning Combinations consist of complementary analogue, power, timing devices and embedded processing, and provide an easy to use architecture, helping to simplify the design process and reduce the design risk for customers in a wide variety of applications.
