LT8640A
Overview
The LT®8640A step-down regulator features Silent Switcher architecture designed to minimize EMI emissions while delivering high efficiency at frequencies up to 3MHz. An ultralow 2.5µA quiescent current-with the output in full regulation-enables applications requiring highest efficiency at very small load currents.
