LT8614 Package is 18-Lead (3mm ×4mm) Plastic QFN.

The LT8614 step-down regulator features Silent Switcher architecture  designed  to  minimize EMI/EMC  emissions while delivering high efficiency at frequencies up to3MHz. Assembled ina3mm ×4mm QFN, the monolithic construction withintegrated 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 below 10mVP-Pat any load, from zero to full current.
