Product Details

DESCRIPTION

The LT®8640 step-down regulator features Silent Switcher architecture designed to minimize EMI/EMC emissions while delivering high efficiency at frequencies up to3MHz. Assembled in a3mm ×4mm QFN, the monolithic construction with integrated power switches and inclusion of all
necessary circuitry yields a solution with a minimal PCB footprint. An ultralow2.5µA quiescent current—with the output in full regulation—enables applications requiring highest efficiency at very small load currents. Transient response remains excellent and output voltage ripple is below10mVP-P at any load, from zero to full current.
