Overview
The LTC3104IDE#TRPBF is a high-efficiency, monolithic synchronous step-down converter manufactured by Analog Devices Inc. It utilizes a current mode architecture to deliver up to 300mA of output current. The device integrates an adjustable 10mA Low Dropout (LDO) regulator designed for powering noise-sensitive circuitry. It operates within an input voltage range of 2.6V to 15V and supports switching frequencies up to 2.6A equivalent capability in specific configurations. The component is housed in a 14-lead DFN package measuring 4mm by 3mm.
Feature Summary
- Integrates a synchronous buck converter with a dedicated adjustable LDO for noise-sensitive loads
- Employs current mode control architecture for efficient power conversion
- Supports wide input voltage ranges suitable for various supply sources
Applications
- Portable battery-powered equipment requiring low noise regulation
- Industrial systems utilizing wide input voltage ranges
- Embedded applications needing combined DC/DC and LDO functionality
Procurement Notes
Verify the exact suffix against official Analog Devices documentation to confirm package type and temperature rating. Ensure compatibility with required thermal dissipation methods for the DFN-14 form factor. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing design integration.
Selection Notes
Select this component when a compact solution combining a synchronous buck converter and a low-noise LDO is required. Consider the 14-DFN package constraints for PCB layout and thermal management. Evaluate the 300mA output limit against peak load requirements to ensure adequate headroom for system stability.
Part Context
This part belongs to the LTC3104 series of power management integrated circuits from Analog Devices. It is designed for applications demanding high efficiency in small footprints. The series typically targets portable electronics and industrial controls where space and power integrity are critical design parameters.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Direct replacements must match the synchronous buck topology, integrated LDO feature, and 14-DFN package dimensions.
