Vicor has introduced Picor PI33XX Cool-PowerZVS buck regulator series with Zero-Voltage Switching (ZVS) topology that can convert input supplies ranging from 8V to 36V to output voltages from 1V to 16V and output current up to 10A for power delivery up to 120W.
Up to six PI33XX buck regulators can use single wire current sharing without the need of any additional components.
ZVS topology purportedly minimize the significant switching losses associated with conventional buck regulators that use hard-switching topologies. PI33XX series buck regulators require only an external inductor and minimal ceramic capacitors for input and output filtering to form a complete high performance regulator.
No frequency compensation, parametric settings or incremental external components are required. A wide operating temperature range of -40°C to 125°C allows for use in almost any environment, according to Vicor.
The Picor Cool-Power portfolio currently consists of the PI31XX series of isolated converters and now the PI33XX series of ZVS buck regulators. The buck regulators are priced at $12.85 for 1,000-unit quantities.
