The latest VIPer11 off-line converter from STMicroelectronics comes with embedded 800V avalanche-rugged MOSFET. It is capable of helping equipment makers to design tougher auxiliary power supplies and power adapters.
Its 26Vdc drain-start voltage allows an ultra-wide line input voltage range and it enhances flexibility in numerous consumer and industrial applications. The logic-level primary MOSFET allows VIPer11 to operate with a wide supply voltage range, from 4.5V up to 30V. This highly efficient 5V output SMPS coupled with features like an integrated high-voltage startup, an error amplifier, and a jittered oscillator that reduces EMI, simplify design and save space and BoM costs will make it a hit.
VIPer11 high-voltage converters enable flyback, boost, or buck/boost power supplies powered directly from the rectified AC line or other DC sources to generate the desired output voltage using a simple voltage divider. High efficiency is assured across a wide load range, even at 5V output voltage thanks to the logic-level MOSFET feature, and industry-leading minimum consumption of 10mW enables extremely low standby power.
The VIPer11 addresses a wide variety of domestic appliances and consumer products, building-automation equipment, small industrial machinery, lighting, smart meters, and motion controls. It is capable of supporting typical maximum rating of 12W in an open-frame SMPS, or 10W in an enclosed adapter. Users also leverage support from development tools including evaluation kits, application notes, spice models and eDesign simulation tool that help evaluate its innovative features.
