LTC3882EUJ#TRPBF

DC DC Switching Controllers Overview

The LTC3882EUJ#TRPBF is a dual-channel PolyPhase DC/DC synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with a fixed 500kHz switching frequency and supports an input voltage range of 3V to 13.8V for the Vcc/Vdd supply. The device features two independent output channels, delivering PWM signals for external power stage control. It utilizes I2C and PMBus serial interfaces for digital power system management. The component is housed in a 40-WFQFN (6x6mm) package with an exposed pad, designed for surface-mount installation.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the EUJ variant corresponds to the specified temperature grade and package dimensions. Ensure compatibility with the target PCB footprint for the 40-QFN package. Validate that the application circuit supports the required input voltage range relative to the controller's Vcc supply specifications.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring dual independent buck outputs managed via digital protocols. The fixed 500kHz frequency balances efficiency and component size. Consider the need for external DrMOS or discrete MOSFETs as the device provides only gate drive signals. Evaluate thermal requirements based on the expected load current and ambient conditions within the 40-QFN enclosure.
