LTC3776EGN#TRPBF

Special Purpose Regulators Overview

The LTC3776EGN#TRPBF is a dual-phase synchronous step-down controller from Analog Devices, designed for high-efficiency power conversion in DDR and other memory applications. It operates with an input voltage range of 2.75V to 9.8V and provides two independent outputs adjustable from 0.3V to 9.8V. The device utilizes a No RSENSE constant frequency current mode architecture, eliminating the need for external sense resistors. It supports surface mount installation in a 28-SSOP package and functions within a temperature range of -40°C to 85°C.

Special Purpose Regulators Feature Summary

• No RSENSE constant frequency current mode architecture removes the necessity for sense resistors
• Dual-phase synchronous buck control optimized for DDR and memory loads
• Wide input voltage range supporting 2.75V to 9.8V sources

Special Purpose Regulators Applications

• DDR memory power supplies
• High-density point-of-load regulation
• Portable electronic devices requiring efficient step-down conversion

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Check for obsolescence notices or lifecycle changes on the official Analog Devices website. Ensure storage conditions meet specified humidity and temperature limits to prevent moisture sensitivity issues during assembly.

Special Purpose Regulators Selection Notes

Select this controller when designing systems requiring precise current sharing without sense resistor losses. Consider the 28-SSOP package constraints for PCB layout efficiency. Evaluate thermal performance requirements given the operating temperature range. Compare against single-phase alternatives if lower output current suffices for the specific application load profile.

Special Purpose Regulators Part Context

This component belongs to the LTC3776 family of dual-phase controllers. It shares architectural similarities with other No RSENSE devices but is specifically tuned for low-voltage, high-current memory applications. The EG suffix indicates the extended temperature grade, while GN#TRPBF denotes the SSOP package and tape-and-reel packaging format.
