The 300-W, 8 A-rated i7C nonisolated dc-dc converters have an input range of 9 to 53 Vdc and output that can be adjusted from 9.6 to 48 V. The product’s topology enables a seamless transition from buck (voltage reduction) to boost (voltage increase) operation. The converter can generate additional high-power outputs from existing 12-, 24-, 36- or 48-V system voltages in such applications as test and measurement and battery-powered equipment. With efficiencies of up to 97%, power losses are minimized, allowing the product to operate and deliver high useable power in demanding thermal environments. Under light load conditions, its control techniques reduce power dissipation significantly.
