LGA50D Series

The LGA50D is a non-isolated DC-DC converter that is designed for cost and space sensitive applications.

This non-isolated unit offers two independent and configurable 25 amp, 50 watt outputs, which can also be combined to a single configurable 50 amp, 100 watt output. With a footprint of 1 x 0.5 inches or 25.4 x 12.5 mm.

The module offers two independent and configurable 25 amp, 50 watt outputs, which can also be combined to a single configurable 50 amp, 100 watt output. You can generate higher current rated rails by connecting up to 4 units in parallel so that up to 200 amps can be supplied as a single power rail.

The input voltage and output voltage specifications remain the same in any configuration, so the input is defined as 7.5 V to 14 V and the output voltage can always be adjusted within the range of 0.6 V to 5.2 Vdc at a maximum efficiency of 95.5% by either PMBus or via external resistor configuration.

The LGA50D is a unit that has 3 different form-factors, including a low-profil version. They are applied in applications by surface mount technology via either block-pin or LGA terminations and can withstand reflow oven temperatures and is supplied in tape-and-reel packaging for simplest production management.
