IMS 2026: noise-free switcher demo
A DC-DC switching supply with no switching noise, delivered at the intrinsic noise floor.
Silent Switcher series
Silent Switcher EMI, part 1: why filter placement matters
With Harmony placed next to the inductor of an LT8622S/LT8624S, part of the radiated energy bypasses the filter and couples into VOUT.
Silent Switcher EMI, part 2: one filter at the point of load
A single TSNJ-5A6L26 at the point of load restores the rail to the Silent Switcher’s own noise floor, and even lower.
LT8622S switching noise, part 1: measuring ripple to 6 GHz
The same rail measures 4 mVp-p on a 1.5 GHz scope and 10 mVp-p on a 6 GHz Keysight Infiniium MXR.
LT8622S switching noise, part 2: the Silent Switcher becomes noise-free
Harmony takes the 2 MHz fundamental from about −59 dBm to −97 dBm (≈ 8.9 µVp-p) and removes microwave spurs.

Overview of the Harmony PI Filter
What DC power delivery at the intrinsic noise floor means for power-supply-induced jitter and AI hardware.
Applications
GPS: 10× smaller positioning errors with TransSiP PI
Two identical golden-reference receivers logged for 24 hours on one antenna. Worst-case error falls from 2.5 km to about 200 m.
GPS sports watch: 5× more battery life
A faster time to first fix means less energy spent in the most power-hungry phase of GNSS.
