Powergood Offers 1/16 Brick DC-DC Converters For Telecom, Datacom & Medical Applications

February 14, 2008 by Jeff Shepard

The Powergood (Small Tech. Research Group) announced the addition of the EST series of isolated dc-dc converters to its portfolio of isolated dc-dc converters for highspeed networking, telecommunications, and computing applications. The 1/16 brick (1.3 x 0.9" footprint) parts are capable of delivering up to 50W of output power at higher voltages, or up to 20A of output current at an output of 1.8Vdc.

The devices are designed to operate efficiently over a 4:1(2:1) input range of 18 to 75Vdc, facilitating their employment on boards with industry standard bus voltages of 24, 48 or 60V. Their wide input range permits the use of single power system designs, which are capable of operating in an extensive array of environments. The series is RoHS compliant and withstand a basic isolation voltage from input to output of 2250Vdc.

The open frame construction of the EST series, combined with its input voltage range and footprint of less than 1.2-square inches, makes it appropriate for use in a wide assortment of networking, telecom, wireless and industrial designs requiring tight board spacing. The most common employment is on PC boards in mobile/optical switches, high capacity network routers, high-end datacom and medical systems, as well as in a variety of systems using distributed power architecture.

EST converters boast fixed frequency synchronous rectification control for high efficiency, together with positive/negative remote sense, remote on/off logic, and +/-10% output trim. Protection features include input and output over-voltage protection, over-temperature protection, current limit and short circuit protection, and under voltage lockout. They are provided with either active-high or active-low on/off polarity. Modules operate over an ambient temperature range of -40 to +85°C. The standard lead time for quantity orders is from stock to 6 weeks. Samples are available immediately.
