LT8640A Step-Down Regulators

Analog Devices Inc. LT8640A Step-Down Regulators are designed with Silent Switcher^® architecture to minimize EMI emissions and to spread spectrum frequency modulation. These regulators deliver high efficiency at frequencies up to 3MHz and offer an ultralow 2.5µA quiescent current. The LT8640A regulators can operate in different modes including burst mode, spread spectrum mode, synchronization to an external clock, and forced continuous mode of operations. These synchronous step-down regulators allow high V_IN to low V_OUT conversion at high frequency with a fast minimum switch-on time of 30ns. The LT8640A regulators are ideally used in applications that require high efficiency at very small load currents including automotive and industrial supplies.
