Description

General part information

LT8625S Series

The LT8625S synchronous step-down regulator features third-generation Silent Switcher technology which 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 LT8625S is ideal for high current, noise sensitive applications which benefit from the high efficiency of a synchronous switching regulator.ApplicationsRF Power Suppliers: PLLs, VCOs, Mixers, LNAs, PAsHigh Speed/High Precision ADCs/DACsLow Noise Instrumentation
