nn 32-Pin (5mm × 5mm) QFN 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. APPLICATIONS The LTC7821 can be easily paralleled to provide higher
output currents with its accurate current sharing capability
and frequency synchronization function. nn Intermediate Bus Converters
