LGA80D Series
Active
Digital Dual Output Non-Isolated Converter
The LGA80D non-isolated DC-DC converter series is designed for cost- and space-sensitive applications. The dual-output converters offer configurable two independent 40 A, 100 W or single 80 A, 200 W outputs. The series allows paralleling of up to four units to obtain a power rail up to 320 A. Input voltage range is 7.5 to 14 VDC and output 0.6 to 5.2 VDC adjustable via PMBus or external resistor with maximum efficiency of 95.5%. With a footprint of 1 x 0.5 inches (25.4 x 12.5 mm), the LGA80D withstands reflow oven temperatures for surface-mount application and is available in tape-and-reel packaging.

LGA80D Non-isolated DC-DC Converter
Jun 14, 2016
The Artesyn LGA80D dc-dc module offers one of the highest current density ratings in the industry and market-leading efficiency of 95.5% typical. With a footprint of just 1 x 0.5 inches or 25.4 x 12.5mm, this innovative non-isolated unit offers two independent and configurable 40 amp, 100 watt outputs, which can also be combined to a single configurable 80 amp, 200 watt output. Design engineers can also generate higher current rated rails by connecting up to 4 units in parallel so that up to 320 amps can be supplied as a single power rail.
Both analog control and digital control functions are enabled on this unit, so the LGA80D can be controlled with resistors or controlled and monitored by using the industry-standard PMBus digital interface. Applications such as graphics, data or video processing, using high power devices, such as server processors, FPGAs, supercomputers, network, storage and telecom equipment, can benefit from the current density, efficiency and flexibility of control of Artesyn’s LGA80D digital dc-dc converter.
