LTC1704EGN#TRPBF

Overview

The LTC1704EGN#TRPBF is a synchronous switching regulator controller combined with a linear regulator controller, manufactured by Analog Devices Inc. It operates at a fixed 550kHz switching frequency and supports two output step-down (buck) converters alongside one linear (LDO) output. The device is housed in a 16-lead SSOP package and is designed for surface-mount installation. This integrated power management IC provides efficient voltage regulation suitable for applications requiring multiple regulated rails from a single controller unit.

Feature Summary

• Integrates synchronous buck switching controller with linear regulator controller
• Supports dual step-down outputs and one LDO output
• Operates at a fixed 550kHz switching frequency

Applications

• Portable electronics requiring multi-rail power supplies
• Industrial control systems needing mixed switching and linear regulation
• Communication equipment with strict space constraints

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. to ensure authenticity. Check current availability status as supply may be limited or subject to factory orders. Ensure the SSOP-16 package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a design requires both high-efficiency switching regulation and low-noise linear regulation in a compact form factor. The fixed 550kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance of the SSOP-16 package relative to the expected load currents for both the buck and LDO sections during system integration.

Part Context

This part belongs to the LTC1704 series of power management ICs from Analog Devices. It is functionally similar to the LTC1704EGN#PBF but differs in packaging format, with the TRPBF suffix denoting reel-based distribution. The series is characterized by combining switching and linear control capabilities to simplify board layout and reduce component count in complex power architectures.

Replacement Considerations

The LTC1704EGN#PBF serves as a direct pin-compatible alternative, differing primarily in the bulk packaging format rather than electrical characteristics. Verify that any substitute maintains the same 16-SSOP footprint and 550kHz operating frequency to ensure compatibility with existing designs.
