Description

General part information

LTC3624LTC3624-2 Series

The LTC3624/LTC3624-2 is a high efficiency 17V, 2A synchronous monolithic step-down regulator. The switching frequency is fixed to 1MHz (LTC3624) or 2.25MHz (LTC3624-2) with a ±40% synchronization range. The regulator features ultralow quiescent current and high efficiency over a wide VOUTrange.The step-down regulator operates from an input voltage range of 2.7V to 17V and provides an adjustable output range from 0.6V to VINwhile delivering up to 2A of output current. A user-selectable mode input is provided to allow the user to trade off 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.LTC3624/LTC3624-2 OptionsPart NumberFrequencyVOUTLTC36241MHzAdjustableLTC3624-3.31MHz3.3VLTC3624-51MHz5VLTC3624-22.25MHzAdjustableLTC3624-23.32.25MHz3.3LTC3624-252.25MHz5VApplicationsBattery Powered EquipmentPortable InstrumentationEmergency RadiosGeneral Purpose Step-Down Supplies
