DC DC Switching Controllers datasheet and documents for LTC3828EUH

LTC3828EUH

DC DC Switching Controllers Overview

The LTC3828EUH 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 20µA. It is housed in a 32-lead QFN package (5x5mm) and functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

Dual independent outputs with synchronized phase control for noise reduction
Precision tracking capability via dedicated TRACK/SS pins for startup sequencing
Constant frequency current mode architecture with soft-start functionality

DC DC Switching Controllers Applications

High-density point-of-load power supplies
Distributed DC power systems requiring multiple rails
Battery-operated digital devices needing low quiescent current
Automotive always-on systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and lead times prior to ordering.

DC DC Switching Controllers Selection Notes

Select this controller when designing systems requiring two independent regulated outputs from a single high-voltage rail. The wide input voltage range accommodates various bus architectures. Consider the thermal performance of the QFN package and ensure adequate PCB layout for high-current switching nodes to maintain efficiency and stability.

DC DC Switching Controllers Part Context

This component belongs to the PolyPhase series of power management ICs designed for high-efficiency step-down conversion. It complements other controllers in the family by offering dual-channel integration, reducing component count compared to using two separate single-phase controllers for similar applications.
