LTC1873EG#PBF

DC DC Switching Controllers Overview

The LTC1873EG#PBF is a dual-phase synchronous step-down switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 36 V and supports output currents up to 25 A across two outputs. The device features a fixed switching frequency of 550 kHz and includes a 5-bit voltage identification interface for programmable output settings between 1.3 V and 3.5 V. Packaged in a 28-lead SSOP, it functions efficiently within an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture for high-current step-down regulation
• Integrated 5-bit VID interface for precise output voltage selection
• Synchronous rectification with integrated gate drivers

DC DC Switching Controllers Applications

• High-density point-of-load power supplies
• Industrial equipment requiring multi-rail distribution
• Telecommunications infrastructure power systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with required thermal management solutions for the SSOP-28 package. Confirm RoHS compliance status through current manufacturer declarations before integration into final assemblies.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring dual independent low-voltage rails from a single higher-voltage source. The fixed 550 kHz frequency allows for compact passive component selection. Evaluate thermal performance requirements carefully due to the dense pinout and high current capabilities inherent to the dual-phase topology.

DC DC Switching Controllers Part Context

This part belongs to the LTC1873 series of dual-phase controllers designed for efficient power conversion. It complements other Linear Technology-derived PMICs by offering synchronized operation capabilities. The EG#PBF designation indicates a lead-free, halogen-free variant suitable for modern manufacturing environments requiring strict environmental compliance.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC1873EG#TRPBF for reel-based assembly needs. Cross-reference with the LTC1876 series if three-phase or boost functionality is required instead of dual buck regulation.
