LTC3104IDE#PBF

Overview

The LTC3104IDE#PBF is a high-efficiency, monolithic synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It features an integrated low-dropout linear regulator (LDO) and operates with a fixed switching frequency of 1.2 MHz. The device supports an input voltage range from 2.5 V to 15 V and provides an adjustable output voltage between 0.6 V and 13.8 V. It delivers a maximum output current of 300 mA while maintaining a typical quiescent current of 2.6 µA in Burst Mode operation. The integrated LDO offers a programmable output current up to 10 mA. The component is housed in a thermally enhanced 16-lead DFN package measuring 3 mm x 4 mm.

Feature Summary

• Integrates a synchronous buck converter with a dedicated 10 mA LDO for noise-sensitive loads
• Supports user-selectable Auto Burst Mode or Forced Continuous PWM operation
• Features internal compensation and precise programmable RUN pin threshold

Applications

• Remote sensor networks
• Distributed power systems
• Energy harvesting applications
• Portable instruments

Procurement Notes

Verify the specific suffix 'IDE' against official Analog Devices documentation to confirm temperature grade and package variant. Ensure compatibility with the intended thermal management solution given the DFN form factor. Confirm RoHS compliance status through the manufacturer's latest material declaration before finalizing procurement specifications.

Selection Notes

Select this component when designing battery-powered systems requiring ultra-low standby current. The choice between Auto Burst Mode and Forced Continuous Mode depends on whether minimizing no-load power consumption or reducing output ripple noise is the primary design constraint. Verify that the required output voltage falls within the supported 0.6 V to 13.8 V range.
