LTC3822EDD-1

DC DC Switching Controllers Overview

The LTC3822EDD-1#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75 V to 4.5 V and supports output voltages from 600 mV to 4.45 V. The device delivers up to 20 A of output current with a single output configuration. Switching frequency is adjustable between 250 kHz and 750 kHz, while quiescent supply current is specified at 360 uA. It functions in the -40°C to +85°C temperature range and utilizes a DFN-12 surface-mount package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF against official Analog Devices documentation to confirm lead-free compliance and RoHS status. Confirm that the DFN-12 package matches your PCB footprint requirements. Ensure the input voltage range aligns with your system's power source specifications before procurement.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring high efficiency in low-voltage environments. The absence of current sense resistors simplifies the bill of materials. Verify that the required output current does not exceed the 20 A limit under your thermal conditions. Consider the DFN-12 package size constraints during layout design.
