LTC3676ELXE-1#PBF

Special Purpose Regulators Overview

The LTC3676ELXE-1#PBF is a power management integrated circuit designed for application processors, manufactured by Analog Devices Inc. It features seven buck converter outputs housed in an LQFP-48 package. The device operates with an input voltage range of 2.7 V to 5.5 V and provides adjustable output voltages from 800 mV to 5.5 V. Each regulator supports up to 2.5 A of output current. The switching frequency is programmable between 1.125 MHz and 2.25 MHz. It includes a shutdown function and has a quiescent current of 23 uA. The component is rated for operation between -40°C and +125°C.

Special Purpose Regulators Feature Summary

• Integrates seven independent synchronous buck converters within a single IC.

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'E' against official Analog Devices documentation to confirm temperature grade or revision status. Confirm availability through authorized distributors as supply may be limited. Ensure compatibility with required PCB footprint for the LQFP-48 package during procurement planning.

Special Purpose Regulators Selection Notes

Select this component when multiple low-voltage rails are required for a central processing unit. Compare against the standard LTC3676 if the '-1' variant offers distinct pinout or feature differences relevant to the design. Evaluate thermal performance requirements given the high integration density in the LQFP-48 package.

Special Purpose Regulators Part Context

This part belongs to the LTC3676 family of PMICs. It shares core architecture with variants like the LTC3676ILXE-1#PBF but differs in package or industrial rating specifications. The family is positioned as a comprehensive solution for multi-rail processor power needs.

Special Purpose Regulators Replacement Considerations

LTC3676ILXE-1#PBF is a documented variant within the same family. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
