These 12.5-A 300-W rated models have been added to the i7C nonisolated dc-dc converter series. With an input range of 9 to 53 Vdc, the output can be adjusted from 5 to 28 V. The topology enables a seamless transition from buck (voltage reduction) to boost (voltage increase) operation. The series is well-suited for generating additional high power outputs from existing 12-, 24-, 36- or 48-V system voltages. Efficiencies of up to 96% minimize power losses, allowing the product to operate and deliver high useable power in demanding thermal environments. Under light load conditions, the converter’s control techniques reduce power dissipation.
