The Vicor PI3740-00-LGIZ is a switching Voltage Regulator using a buck-boost topology with a single output, operating from an input of 8V to 60V at a 1M Hz switching frequency. Because it is buck-boost rather than buck only, the output voltage can be set above or below the input, which lets the regulator hold regulation through a wide input excursion. The device stands 2.63mm tall, is rated to a 115°C maximum junction temperature over a -40°C to 115°C operating range, and is RoHS compliant. Attribute coverage on this record is limited to ten fields and does not include the output voltage or current rating.

The PI3740-00-LGIZ is used where the input rail can swing above and below the required output, which is exactly the condition a buck-only converter cannot handle. Typical applications include 24V and 48V industrial and telecom rails that must hold a regulated intermediate voltage through brownout and surge, battery-powered systems whose pack voltage crosses the output as it discharges, transportation and automotive electronics subject to load dump and cold crank, and LED driver and supercapacitor charging circuits. Vicor power components are generally specified for high power density and low profile, so they suit sealed enclosures and card-edge designs where a discrete converter would not fit. Note that output voltage and current ratings are not populated in this record; confirm them against the manufacturer datasheet before designing in.
