ADI’s Silent Switchers offer high efficiency at high switching frequencies while maintaining ultralow EMI emissions.
These regulators bring new levels of performance for synchronous stepdown DC/DC converters.
Maximum input voltages ranging from 8 V to 65 V make them ideal for applications that require from 1 A up to 15 A of output current, including automotive, industrial and communications systems applications.
The Silent Switcher family uses special design and packaging techniques to offer 95% efficiency at 2 MHz while easily passing the CISPR 25 Class 5 Peak EMI limits.
Silent Switcher 2 adds internal bypass capacitors and an integrated substrate to further improve EMI that is not sensitive to PCB layout, simplifying designs and reducing performance risks even when using two-layer PC boards.
The featured LT8650S is a dual-channel, 4 A, 42 V, synchronous stepdown Silent Switcher 2 with a 6.2 μA quiescent current.
