Reduced Switching Losses Enable up to 98% Peak Efficiency and High Frequency Operation up to 36Vin
ANDOVER, MA--(Marketwire - Jul 17, 2012) - Vicor Corporation (
The use of a ZVS topology enables high-frequency operation that maximizes efficiency by minimizing the significant switching losses associated with conventional buck regulators that use hard-switching topologies. The high switching frequency of the PI33XX series also reduces the size of the external filtering components, improving power density while enabling fast dynamic response to line and load transients. The PI33XX series sustains high switching frequency all the way up to the rated input voltage without sacrificing efficiency and, with its 20ns minimum on-time, supports large step down conversions up to 36Vin.
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.
For designers challenged by complex distribution power schemes, Picor PI33XX Cool-Power ZVS buck regulators are the only buck regulators in their class to offer an optional I2C™ extended fault telemetry capability allowing for six distinct types of fault reporting. Additional device-programmable I2C features include margining, enable pin logic polarity, and phase delay. Device programming is easily performed via the Cool-Power Development Tool.
"The introduction of the Picor PI33XX Cool-Power ZVS buck regulator series allows designers to achieve high performance point of load power on the board," said Robert Gendron, Vice President, Marketing and Business Development, Vicor. "Integrating a ZVS soft switching topology within a point of load buck regulator creates a new performance standard for the industry. Coupled with Vicor's broad range of solutions for power delivery to the board, we are enabling optimal power efficiency throughout the power chain -- all the way to the point of load."
About Picor Cool-Power
The Picor Cool-Power portfolio currently consists of the PI31XX series of isolated converters and now the PI33XX series of ZVS buck regulators. The PI33XX series is the initial offering of what will be a comprehensive product family of high density, high performance ZVS point of load regulators. Future products in the family will include additional ZVS buck regulators with higher voltage and higher current capability, ZVS buck-boost regulators, and ZVS boost regulators, all expected to set new industry benchmarks in efficiency and density.
