Hot sale original LT8614IUDC TRPBF Buck Switching Regulator IC Positive Adjustable 3.3V 1 Output 4A 20-WFQFN

Description
The LT®8614 step-down regulator features Silent Switcher architecture designed to minimize EMI emissions while
delivering high efficiency at frequencies up to 3MHz. Assembled in a 3mm × 4mm QFN, the monolithic construction with integrated power switches and inclusion of all necessary circuitry yields a solution with a minimal PCB footprint. An ultralow 2.5µA 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 below 10mVP-P at any load, from zero to full current.
