LTC1702CGN#PBF

DC DC Switching Controllers Overview

The LTC1702CGN#PBF is a dual synchronous switching regulator controller manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 550kHz and supports an input voltage range of 3V to 7V. The device provides two independent output phases, suitable for buck topology applications. It is housed in a 24-lead SSOP package with a narrow 0.15-inch width. The component is designed for efficient power conversion, achieving up to 90% efficiency in typical configurations.

DC DC Switching Controllers Feature Summary

• Dual synchronous control architecture for independent phase management
• Fixed 550kHz switching frequency for optimized passive component size
• Wide input voltage compatibility from 3V to 7V
• Integrated high-side and low-side gate drivers

DC DC Switching Controllers Applications

• Point-of-load regulation for digital signal processors
• Multi-rail power distribution systems
• Industrial control board voltage translation
• Telecommunications equipment power supplies

DC DC Switching Controllers Procurement Notes

Verify the exact suffix designation when ordering, as #PBF indicates lead-free RoHS compliance. Confirm package variant availability, as tape-and-reel options may exist for automated assembly. Ensure the supplier source is authorized to guarantee genuine components. Cross-reference the full part number against official Analog Devices documentation to confirm pinout and electrical specifications match the design requirements.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring two isolated or non-isolated buck outputs from a single intermediate bus voltage. The fixed 550kHz frequency simplifies filter design compared to adjustable frequency alternatives. Consider thermal performance within the SSOP package when determining heat dissipation needs. Evaluate the 3V to 7V input range against the system's available power rails to ensure adequate headroom for the desired output voltages.

DC DC Switching Controllers Part Context

This component belongs to the LTC1702 family of dual synchronous regulators. It serves as a core control IC for multi-phase power delivery systems. The CGN variant specifies the commercial temperature range and specific packaging. Related evaluation boards like DC473A are available to assist in circuit validation and performance testing during the development phase.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include LTC1702ACGN#PBF and LTC1702IGN#PBF, which share the same functional interface but differ in temperature ratings. Verify that any replacement maintains the 24-SSOP footprint and 550kHz operating characteristics to ensure compatibility with existing PCB layouts and timing constraints.
