Bel Adds New 1/16 Brick DC-DC Converters for Telecom, Datacom and Medical Applications
The Bel Power division of Bel Fuse Inc. announced the addition of the SRSB-40U Series of isolated dc-dc converters to their growing portfolio of isolated and non-isolated power dc-dc converters for high-speed networking, telecommunications, and computing applications.
The 1/16 brick (1.3" x 0.9" footprint) parts are capable of delivering up to 40W of output power at higher voltages, or up to 18A of output current at an output of 1.2V. The devices are designed to operate efficiently over a 4:1 input range of 18 � 75 Vdc, facilitating their employment on boards with industry standard bus voltages of 24, 48 or 60V. Notably, their ultra-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 6/6 compliant, and carries a full set of international safety approvals including UL, UL60950, and IEC/EN60950.
The open frame construction of the SRSB-40U 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 telecom, networking, wireless and industrial designs requiring tight inter-board spacing. Among the modules’ 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.
Bel Power’s new 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. The parts are available in both SMT and through-hole designs, and in seven distinct output voltages ranging from 1.2 to 12V. 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.
Pricing for Bel’s SRSB-40U Series of isolated dc-dc converter starts at $24.95 each in quantities of 1,000. The standard lead time for quantity orders is from stock to 12 weeks. Samples are available immediately.
