LGA50D Series
Active
100 W Digital Non-Isolated DC-DC Converters
Designed for cost and space-sensitive applications, the LGA50D series of non-isolated DC-DC converters offers dual outputs configurable as two independent 25 A, 50 W outputs or single 50 A, 100 W. You can parallel up to four units to generate a higher current-rated rail up to 200 A. The input voltage range is rated at 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 LGA50D is available in three form factors, including a low-profile version. The series withstands reflow oven temperatures for surface-mount application via block-pin or LGA terminations and is available in tape-and-reel packaging.

LGA50D Product Training Module
Jan 10, 2019
The LGA50D is a surface-mount, non-isolated DC-DC converter with two independently controllable channels rated at up to twenty-five amps for each channel. It offers the user an extremely high power conversion density when application space is at a premium. The LGA50D can be controlled and monitored by digital communication via the standard PMBus commands but, if this is not required, it can be configured with external resistors. The two outputs can also be connected to give a single output rated up to fifty amps.
This presentation provides an overview to the LGA50D unit including a review of the features and benefits. It will also highlight the widely configurable nature of the device as well as discussing possible target markets and applications.
