PoL DC/DC converter delivers 30% higher power density

Advanced Energy has expanded its LGA family with the release of the Artesyn LGA110D, a 110 amp-rated, non-isolated digital point-of-load (PoL) DC/DC converter. The company claims the  LGA110D delivers a higher current rating at 30% higher power conversion density than DC/DC converters in its class. Target applications for the PoL DC/DC converter include a broad range of industrial, medical, telecom, and IT infrastructure markets.

PoL DC/DC converter delivers 30% higher power densityDue to its power density, the LGA110D increases operational efficiency to more than 96%, according to Joe Voyles, vice president of marketing, industrial power conversion products at Advanced Energy. “The higher peak efficiency reduces power dissipation by 15% compared to older generations with the same small form factor.”

The LGA110D PoL DC/DC converter offers current density of 220 amps per square inch. It features two independently controlled 55-amp/175-watt outputs, which means fewer power converters are needed in multiple-channel or high-current applications, said Advanced Energy.

The dual outputs can be selected as independent, configured to a single output or synchronized with up to three other LGA110D PoL DC/DC converters. This saves PCB space and reduces overall system cost, while addressing the increasing current requirements in FPGA or ASIC devices used in complex applications, said the company.

With both analog and digital control functions, the LGA110D can be controlled with external resistors or the PMBus digital interface that features additional control functions for greater system integration flexibility.
