Renesas Electronics has released the RAA2230XX family of 700 V buck regulators, claimed to deliver better power consumption, noise and EMI suppression over competitive solutions. They are suitable for a wide range of applications, including home appliances, sensing systems such as smoke alarms and gas sensors, whitegoods, power meters and industrial controls.
The buck regulators consume only 10 to 30 mW when idle, helping system designers meet tightening standby power regulations. They feature a switching algorithm which minimises electromagnetic interference (EMI) and eliminates audible noise, such as ‘humming’ or ‘whining’. The regulators also can supply as low as 3.3 V output, enabling designers to eliminate a second-stage low dropout regulator (LDO), saving BOM cost and board space.
The buck regulators feature support for both non-isolated buck and isolated flyback topologies, allowing users to develop multiple types of AC input power supplies. They are available in TSOT23-5, SOIC-8 and SOIC-7 package options, delivering pin-to-pin compatibility with competitors’ products for easy replacement. The family includes 2, 4 and 8 W versions.
