Historically, switch-mode power supplies (SMPS) have been too noisy for noise-sensitive analog-to-digital converters (ADCs), requiring a separate low dropout (LDO) regulator. Recent advancements in SMPS technology, including Silent Switcher®architecture and electromagnetic...
A controller, in response to a change detected in a switching frequency of the switch, reduces audible noise generated by the power supply by at least one of: adjusting the reference voltage; adjusting the current sense voltage; or adjusting a resistance used to generate the sensed voltage....
Noise on switch mode power supplies (SMPSs) sometimes gets a bum rap. Noise on switch mode power supplies (SMPSs) sometimes gets a bum rap. I was evaluating the voltage noise on a simple low-cost switch-mode power supply (SMPS) and almost fell for the widespread poor reputation thes...
