Meeting the increasing LED Lighting demands with 12 Volts to 48 Volts

Vicor Cool-Power ZVS buck and buck-boost deliver higher power, higher efficiency, and low profile for powering bright outdoor and fine pitch indoor panels and displays. Cool-Power regulators are capable of supporting existing 12 and 24 Volt power distribution architectures, while newer 48 Volt input regulators have enabled new cutting-edge designs to combine the benefits of high power density and efficiency with the benefits of lower distribution losses and reduction of conversion stages. New 48 Volt devices enable direct point-of-load conversion from 48 Volt to LED/LED Driver voltages down to 2.2 V at up to 96% efficiency with power levels up to 22 A in a compact 10 x 14 x 2.5 mm package. Cool-Power regulators are used in a broad range of LED panels and displays, everything from small front-of-bus destination panels, to large indoor commercial displays, to very large side-of-building multi-kilowatt architectural displays.
