The LT®8622S/LT®8624Ssynchronous 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 LT8622S/LT8624S is ideal for high-current, noise- sensitive applications that benefit from the high efficiency of a synchronous switching regulator.

The LT8636/LT8637synchronous step-down regulator features Silent Switcher architecture designed to minimize EMI emissions while delivering high efficiency at high switching frequencies. Peak current mode control with a 30ns minimum on-time allows high step-down ratios even at high switching frequencies.The LT8636’s ultralow 2.5µA quiescent current—with the output in full regulation—enables applications requiring highest efficiency at very small load currents. The LT8637 has external compensation to enable current sharing and fast transient response at high switching frequencies. A CLKOUT pin enables synchronizing other regulators to the LT8636/LT8637.Burst Mode operation enables ultralow standby current consumption, forced continuous mode can control frequency harmonics across the entire output load range, or spread spectrum operation can further reduce EMI emissions. Soft-start and tracking functionality is accessed via the TR/SS pin, and an accurate input voltage UVLO threshold can be set using the EN/UV pin.ApplicationsAutomotive and Industrial SuppliesGeneral Purpose Step-Down
