DC/DC bus converter module reduces energy and cooling costs

The DC/DC advanced bus converter targets high-end and high-power applications and can handle 1000W of power and 96.2A of peak current.

It is supplied in an industry-standard and low-profile quarter-brick-format. Dimensions are 58.4 x 36.8 x 12.19mm. The module operates from a wide input range of 40 to 60V, and offers multiple, tightly regulated (±2.5%) pre-programmed outputs at 10.4, 12 and 12.5V. It can be factory configured at any voltage between 9.0 to 13.2V.

Hybrid Regulated Ratio (HRR) technology enables better use of the powertrain to deliver high-power conversion across the input voltage range. For applications that operate in high ambient temperatures with limited airflow power conversion is up to 97% efficiency at 53V and half load. The company adds that power losses are kept low.

In addition to use as intermediate bus conversion (IBC), dynamic bus voltage (DBV) and distributed power architectures (DPA), the module is designed to power high-end and high-power applications powered by multi-cell batteries or rectifiers that are commonly used in ICT (Information and Communication Technologies) applications. Other suitable applications are networking and telecommunications equipment, industrial equipment, and server and storage applications.

Delivering higher useable power in high ambient temperature and limited-airflow environments means high reliability for the module, says the company. Although the module comes with a standard baseplate, it can also be connected to a heatsink or coldplate for the most challenging thermal environments.

Key features include dynamic load compensation and support for the latest version (v1.3) of the PMBus communication specification and the Ericsson Power Designer software tool. There is also droop load sharing capability, 1500V I/O isolation, monotonic start-up, remote control, and a range of protection capabilities including over-temperature, output-short-circuit and output-over-voltage.
