DC DC Switching Controllers datasheet and documents for LTC3811EG#TRPBF

LTC3811EG#TRPBF

DC DC Switching Controllers Overview

The LTC3811EG#TRPBF is a multiphase synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 30 V and supports output voltages from 600 mV to 3.3 V. The device delivers up to 20 A of output current through its integrated high-speed control architecture. Key electrical parameters include a switch frequency of 500 kHz, a quiescent current of 20 uA, and a supply current of 10.5 mA. It functions within a temperature range of -40°C to +85°C and utilizes a QFN-38 package for surface mount installation.

DC DC Switching Controllers Feature Summary

Multiphase buck controller architecture for high-current delivery
Integrated high-speed control loop for transient response
Low quiescent current operation for efficiency optimization

DC DC Switching Controllers Applications

Industrial distributed power systems
Telecommunications infrastructure power supplies
Point-of-load regulation for digital processors

DC DC Switching Controllers Procurement Notes

Verify the specific suffix EG against official Analog Devices documentation to confirm tape-and-reel packaging and commercial grade temperature rating. Ensure compatibility with required PCB footprint dimensions for the QFN-38 package. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status via the latest datasheet revision.

DC DC Switching Controllers Selection Notes

Select this component when designing multi-phase power stages requiring precise current sharing and fast transient response. The 500 kHz switching frequency balances component size and efficiency. Verify that the external inductor and capacitor values align with the 20 A output capability and desired ripple specifications. Ensure the input voltage source remains stable within the 4.5 V to 30 V operational window.
