LTC3828EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3828EUH#TRPBF is a dual-output, two-phase synchronous buck controller from Analog Devices. It operates with an input voltage range of 4.5V to 28V and supports output voltages from 800mV to 7V. The device features a switchable frequency between 260kHz and 550kHz and draws a typical quiescent current of 20uA. Packaged in a 32-WFQFN (5x5mm) surface-mount housing, it is designed for high-efficiency power management applications requiring precise regulation.

DC DC Switching Controllers Feature Summary

• Dual-output architecture enabling independent or synchronized control of two separate load rails
• Integrated tracking function allowing one output to follow another during startup or shutdown sequences
• Synchronous rectification topology maximizing conversion efficiency across varying load conditions

DC DC Switching Controllers Applications

• High-density server and workstation power distribution units
• Telecommunications base station equipment requiring multi-rail regulation
• Industrial automation systems with strict thermal constraints

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the EUH variant matches the required 32-QFN package dimensions for your PCB footprint. Ensure the manufacturer is Analog Devices Inc. to guarantee authenticity and performance specifications.

DC DC Switching Controllers Selection Notes

Select this component when a compact solution for dual-rail power delivery is required. The wide input voltage range accommodates various bus architectures. Consider the integrated tracking feature if sequential power-up/down is necessary for system stability. Evaluate thermal requirements based on the QFN package's heat dissipation capabilities.

DC DC Switching Controllers Part Context

This part belongs to the PolyPhase series of DC/DC controllers. It complements other models like the LTC3828EG by offering reel packaging for automated assembly.
