LT86x Synchronous Step-Down Silent Switchers

Analog Devices LT86xx Synchronous Step-Down Regulators feature Silent Switcher® architecture designed to minimize EMI/EMC emissions while delivering high efficiency at frequencies up to 3MHz. Assembled in a 3mm × 4mm QFN package, the monolithic construction with integrated power switches and the inclusion of all necessary circuitry yields a solution with a minimal PCB footprint. An ultra-low 2.5µA quiescent current enables applications requiring the highest efficiency at very small load currents. The transient response remains excellent and output voltage ripple is below 10mVP-P at any load, from zero to full current.
