Power Integrations today announced a new reference design for an 8 W, universal-input auxiliary power supply that achieves zero standby power consumption for appliance applications. Based on a member of Power Integrations’ LinkZero™-LP family of ICs, DER-417 describes a universal-input, 5 V, 1600 mA flyback power supply that consumes less than 4 mW at 230 VAC and provides 1 mW of power in standby mode.
Products such as TVs, appliances, security and monitoring systems and HVAC equipment use power while waiting to be used or while monitoring sensor inputs prior to executing their proper functions. This wasted power amounts to both an environmental cost and an economic cost to households and businesses. Comments Edward Ong, product marketing manager for Power Integrations: "We are moving very close to the ultimate in standby power performance. We think that DER-417 will inspire designers to implement zero-standby auxiliary power supplies for their products – leading to an overall reduction in wasted standby energy."Read today's press release.
