A81805/A81805-1 Synchronous Buck Regulators

Allegro MicroSystems A81805/A81805-1 Synchronous Buck Regulators are 40V synchronous buck regulators with low EMI and 6µA quiescent current that allows high efficiency over a full load of up to 2.5A. The A81805/A81805-1 regulators support a unique architecture that reduces the amount of EMI generated by the switching components to minimize the number of external components.
