LTC1704BEGN#PBF

Overview

The LTC1704BEGN#PBF is a dual-output power management IC from Analog Devices, combining a synchronous buck converter and a low-dropout linear regulator in a single SSOP-16 package. The switching section operates as a step-down controller with a fixed 550 kHz frequency, supporting input voltages from 3.15 V to 5.5 V and delivering up to 25 A output current. The integrated LDO provides a secondary regulated rail. This configuration allows for efficient voltage conversion alongside precise analog supply generation within a compact surface-mount footprint suitable for space-constrained designs.

Feature Summary

• Integrates a high-current synchronous buck converter with an independent low-dropout linear regulator
• Features a fixed 550 kHz switching frequency for optimized external component size
• Supports wide input voltage ranges compatible with standard single-cell battery or bus supplies

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Embedded systems needing combined digital power and sensitive analog supply generation
• Battery-powered equipment utilizing synchronous rectification for efficiency

Procurement Notes

Verify the specific suffix and temperature grade against the official datasheet before ordering. Confirm that the SSOP-16 package dimensions match your PCB footprint requirements. Ensure the input voltage range aligns with your system's power source specifications. Check for any recent manufacturing changes or lifecycle status updates directly from the manufacturer.

Selection Notes

Select this component when both high-efficiency DC-DC conversion and low-noise linear regulation are required in a single package. It is suitable for applications where board space is limited but distinct power domains exist. Consider the thermal performance of the SSOP-16 package under maximum load conditions. Verify compatibility with the required output current capabilities of both the buck and LDO sections.

Part Context

This device belongs to the LTC1704 series of mixed-signal power management solutions. It represents a consolidation strategy by Analog Devices to reduce component count in multi-rail power architectures. The integration of switching and linear technologies addresses the need for efficient bulk power conversion alongside clean power for sensitive circuitry.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify electrical parameters such as switching frequency and output current ratings for any substitute parts. Ensure thermal characteristics and package integrity remain consistent with the original design requirements.
