LINEAR TECHNOLOGY LT8640EUDC#PBF 直流-直流开关降压逐步递减稳压器, 可调, 3.4V-42V输入, 970mV-41.9V输出, 5A输出, QFN-18
The is an adjustable output, constant frequency, synchronous step down silent switcher in 18 pin QFN package. This monolithic ultralow noise current mode step down regulator has silent switcher architecture designed to minimize EMI/EMC emissions while delivering high efficiency at frequencies up to 3MHz. The monolithic construction with integrated power switches and inclusion of all necessary circuitry yields a solution with minimal PCB footprint. An ultralow 2.5µA quiescent current with output in full regulation enables applications requiring highest efficiency at very small load currents. Transient response remains excellent and output voltage ripple is below 10mVP-P at any load from zero to full current. Operation is safe in overload even with saturated inductor. The SYNC/MODE pin selects between burst mode operation, spread spectrum mode, synchronization to an external clock and works with pulse skipping mode.
