LTC3100EUD#TRPBF

Overview

The LTC3100EUD#TRPBF is a triple-rail power management IC from Analog Devices, integrating two synchronous step-down DC/DC converters and one low-dropout (LDO) regulator. It operates with an input voltage range of 2.7V to 5.5V. The switching frequency for the DC/DC converters is fixed at 1.5MHz. Quiescent current is specified as 16µA or 28µA depending on operating mode. The device supports Burst Mode operation for enhanced light-load efficiency. It is housed in a compact 20-lead QFN package.

Feature Summary

• Integrates dual synchronous buck converters and a single LDO regulator for multi-rail supply generation
• Features Burst Mode operation to minimize quiescent current consumption during light loads
• Includes Power Good monitoring signals for system status indication

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Battery-powered systems needing high efficiency at light loads
• Embedded solutions with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against the manufacturer's latest documentation. Confirm RoHS compliance status and lead-free specifications prior to ordering. Ensure the source provides valid traceability for this Analog Devices part number.

Selection Notes

Select this component when a compact solution for generating three distinct voltage rails is required. It is suitable for applications where input voltages remain between 2.7V and 5.5V. Consider its 1.5MHz switching frequency for balancing component size and electromagnetic interference.

Part Context
