Description
General part information
LTC3622 Series
The LTC3622 is a dual 1A output, high efficiency synchronous monolithic step-down regulator capable of operating from input supplies up to 17V. The switching frequency is fixed to 1MHz or 2.25MHz with a ±50% synchronization range to an external clock. The regulator features ultralow quiescent current and high efficiency over a wide output voltage range.The step-down regulators operate from an input voltage range of 2.7V to 17V and provide an adjustable output from 0.6V to VIN while 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 ripple noise. The switching regulators can be synchronized to an external clock. Furthermore, fixed VOUToptions are available to eliminate the external feedback resistors.LTC3622 OptionsPart NameFrequencyVOUTLTC36221.00MHzAdjustableLTC3622-22.25MHzAdjustableLTC3622-23/52.25MHZ5V/3.3VApplicationsBattery Powered SystemsPoint-of-Load SuppliesPortable – Handheld Scanners
