LTC7821 Datasheet (Analog Devices) - Hybrid Step-Down Synchronous Controller

LTC7821, Hybrid Step-Down Synchronous Controller

The LTC®7821 uses a proprietary architecture that merges a soft switching charge pump topology with a synchronous step-down converter to provide superior efficiency and EMI performance compared to traditional switching architectures.

In a typical 48V to 12V application, efficiency of greater than 97
