LTC3624IDD-2#PBF

LINEAR TECHNOLOGY  LTC3624IDD-2#PBF  直流-直流开关降压逐步递减稳压器, 可调, 2.7V-17V输入, 600mV-17V输出, 2A输出, DFN-8

The LTC3624 series synchronous monolithic Step-down Regulator for use with battery-powered equipment. The switching frequency is fixed to 2.25MHz with a ±40% synchronization range. The regulator features ultralow quiescent current and high efficiency over a wide VOUT range. The step-down regulator operates from an input voltage range of 2.7 to 17V and provides an adjustable output range from 0.6V to VIN while delivering up to 2A of output current. A user-selectable mode input is provided to allow the user to tradeoff ripple noise for light load efficiency. Burst Mode® operation provides the highest efficiency at light loads, while pulse-skipping mode provides the lowest voltage ripple. The MODE pin can also be used to sync the switching frequency to an external clock.
