LTC7821 Hybrid Step-Down Synchronous Controllers

Analog Devices Inc. LTC7821 Hybrid Step-Down Synchronous Controllers feature a proprietary architecture that combines a soft-switching charge pump topology with a synchronous step-down converter to offer exceptional efficiency and EMI performance compared to traditional switching architectures. The LTC7821 Hybrid Controllers operate with a 3x higher switching frequency, can achieve up to a 3% higher efficiency, and reduce the DC-DC converter solution size up to 50% compared to traditional step-down solutions. In addition, the LTC7821 Hybrid Controllers have low EMI and reduced MOSFET stress due to a soft-switched front end. The LTC7821 Hybrid Controllers are ideally suited for next-generation non-isolated intermediate bus applications in power distribution, datacom and, telecom as well as emerging 48V automotive systems.
