DLynx II board-level power conversion capabilities expanded with digital control

The GE DLynx II family of PoLs is a second-generation digital, non-isolated voltage converters that offer improved performance, additional digital features, greater density and a broader range of applications — enabled by higher current PoLs — compared to previous products. The DLynx II family of PoL modules offers a range of products from 4 to 170 A. The model TJT170, at 170 A, is the highest current PoL unit available. The unit offers an efficiency of 96% and 50% load step transients of <20 mV. The solution set also includes the micro-sized UJT035 and pico-sized PJT020 modules, which offer class-leading current density in industry-standard (DOSA-compatible) footprints.

The DLynx II PoL modules provide board designers with a variety of benefits compared to the previous generation of DLynx solutions, including more accurate voltage control often needed in today’s advanced, high-performance processors. They also feature digital compensation, which enables increased flexibility for wider operating conditions, providing better control in a wide range of applications. These features better enable users to design, troubleshoot and optimize their end products.

The modules use PMBus to help designers realize the benefits of the digital solutions. PMBus enables the DLynx II modules to communicate seamlessly with software tools, such as GE’s Digital Power Insight software, to help users optimize their original board designs and improve the field performances of their final products. Analog versions without PMBus also are available for 7-to-20-A modules.

The DLynx II modules are suite datacom and telecom applications, industrial equipment, control equipment and wireless solutions. For example, the PoL modules can be used in applications such as network routers and switches, optical transceivers, high-performance computers, servers and storage equipment, industrial controls, lasers, industrial automation equipment, automated test equipment, wireless transceivers and robotics.
