ADI Silent Switcher 3 Step-Down Regulator with Ultralow Noise Reference
Candidate for：2024 World Electronics Achievement Awards - Power Management/Voltage Converter
ADI Silent Switcher 3 technology is uniquely designed to combine an ultralow noise reference with Silent Switcher architecture in order to achieve both high efficiency and excellent wideband noise performance.
The innovative ultralow noise architecture provides exceptional low frequency (0.1Hz to 100kHz) output noise performance in a switching regulator. The output voltage can be programmed with a single resistor, resulting in virtually constant output noise independent of output voltage. Silent Switcher architecture minimizes EMI emissions while delivering high efficiency at high switching frequencies. The top of the package features exposed die for optional heat sink attachment which can be used to significantly improve thermal performance. The Silent Switcher 3 is ideal for high current, noise sensitive applications which benefit from the high efficiency of a synchronous switching regulator.
