Product Details

The LT8627SP 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–100kHz) output noise performance in a switching regulator, independent of output voltage. Silent Switcher architecture minimizes EMI emissions while delivering high efficiency at high switching frequencies. 

The LT8627SP is ideal for high current, noise sensitive applications which benefit from the high efficiency of a synchronous switching regulator.
