Power Electronics / Power Management
Vicor added two new buck-boost regulators to its Cool-Power ZVS regulator portfolio. Delivering up to 150 Watts at greater than 97% efficiency, the new PI3741-0x modules incorporate Vicor’s proprietary high-frequency zero voltage switching (ZVS) technology and are an ideal choice for demanding automotive, industrial, test, automation, lighting, battery regulation and telecom applications.
Conventional, hard-switching buck-boost regulators are handicapped by switching losses and exhibit conversion efficiency degradation when operating from a higher voltage input source with extended dynamic range. Vicor’s ZVS buck-boost regulator technology minimises switching losses and maintains high efficiency over the specified input voltage range while enabling high-frequency operation for improved power density and fast dynamic response to line and load transients. The PI3741-0x regulators have a wide operating temperature range of -40°C to 125°C and require only minimal external components to form a complete high-performance regulator.
Both PI3741-0x regulators operate over a wide input voltage range of 21 – 60 V d.c. and integrate a ZVS controller, power switches and support circuitry within a high density, thermally adept, 10 x 14 x 2,5 mm SiP (system-in-package). The PI3741-00 delivers a user-definable output voltage in the range of 21 – 36 V d.c. while the PI3741-01 supports a higher output voltage in the range of 36 – 54 V d.c.
