Description
General part information
LTC3621 Series
The LTC3621/LTC3621-2 is a high efficiency 17V, 1A synchronous monolithic step-down regulator. The switching frequency is fixed to 1MHz or 2.25MHz with a ±40% synchronizing range. The regulator features ultralow quiescent current and high efficiencies 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 1A 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 allow the user to sync the switching frequency to an external clock.LTC3621 OptionsPart NameFrequencyVOUTLTC36211.00MHzAdjustableLTC3621-3.31.00MHz3.3VLTC3621-51.00MHz5VLTC3621-22.25MHzAdjustableLTC3621-23.32.25MHz3.3LTC3621-252.25MHz5VAPPLICATIONSPortable-Handheld ScannersIndustrial and Embedded ComputingAutomotive ApplicationsEmergency Radio
