LT8614HUDC#PBF

LINEAR TECHNOLOGY  LT8614HUDC#PBF  直流-直流开关降压逐步递减稳压器, 可调, 3.4V-42V输入, 970mV-41.8V输出, 4A输出, QFN-18

The is a Step-down Regulator features 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 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 current. Transient response remains excellent and output voltage ripple is below 10mVP-P at any load, from zero to full current. The LT8614 allows high VIN to low VOUT conversion at high frequency with a fast minimum top switch on-time of 30ns. Operation is safe in overload even with a saturated inductor. Essential features are included and easy to use - an open drain PG pin signals when the output is in regulation. The SYNC pin allows clock synchronization and choice of Burst Mode® operation or pulse-skipping mode.
