LT8650S Synchronous Step-Down Silent Switcher® 2

Analog Devices LT8650S Synchronous Step-Down Silent Switcher® 2 is a dual step-down regulator with a wide input voltage range of 3V to 42V, ideal for automotive, industrial, and other step-down applications. The LT8650S features a low 6.2µA quiescent current with the outputs in regulation, a critical feature in automotive environments where always-on systems can drain the battery even when the car is not running. The Silent Switcher®2 architecture of the LT8650S minimizes EMI emissions while delivering high efficiency at high switching frequencies. This includes the integration of bypass capacitors to optimize high-frequency current loops and make it easy to achieve advertised EMI performance by eliminating layout sensitivity.
