Overview
Analog Devices launched Silent Switcher®3, the latest generation of low-noise DC-DC converters, in 2023. These products feature low effective output noise comparable to LDOs, allowing them to supply the power directly even in noise sensitive applications.
LTEC released three reports (1) Die overview analysis report (2) Package analysis report (3) Circuit analysis report. In the circuit analysis report the function, the circuit configuration and identification of low noise switching countermeasures are clarified based on entire die circuit analysis.
