Providing efficiencies of 90% at 5V, 100W and with up to 30% less power dissipation than most standard versions of the product, the RM Series of dc-to-dc converters is only 8 mm high and requires no heatsink, making them well-suited for applications requiring narrow card pitch, such as broadband distribution, ATM exchanges, LANs and multimedia systems. The series offers 30W, 50W and 100W for dc inputs of 36 to 75 vdc.
