Emerson Network Power's extensive range of dc-dc converters includes a number of high-efficiency ultra low profile models for applications where above-board height is severely restricted. There are 5 families of isolated converter spanning a power range of 10 watts to 30 watts, together with a family of 20 watt non-isolated converters. Many of the isolated models have a profile of just 0.17 inches (4.3 mm), and they all offer current sharing for parallel operation.
