Power Management Buck Regulator Positive Output Step-Down DC-DC Controller IC 32-QFN

 

PRODUCT DESCRIPTION

 

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% is attainable with the LTC7821 switching at 500kHz. The same efficiency can only be achieved with a traditional controller switching at one-third the frequency. Higher switching frequencies allow the use of smaller inductances that yield faster transient response and smaller solution size. The LTC7821 can be easily paralleled to provide higher output currents with its accurate current sharing capability and frequency synchronization function.
