LT8638S Synchronous Step-Down Silent Switcher® 2

Analog Devices Inc. LT8638S Synchronous Step-Down Silent Switcher® 2 is a monolithic, constant frequency, current-mode step-down DC-DC converter based on second-generation Silent Switcher technology. This technology minimizes EMI emissions while delivering high efficiency at high switching frequencies. The LT8638S features integrated input capacitors to optimize all the fast current loops inside and maximize EMI performance by reducing layout sensitivity. This performance makes the LT8638S ideal for noise-sensitive applications and environments.
