LTC1702IGN#TRPBF

DC DC Switching Controllers Overview

The LTC1702IGN#TRPBF is a dual-output synchronous buck switching regulator controller manufactured by Analog Devices Inc. It operates from a 3V to 7V input supply and delivers two independent regulated outputs, typically configured for 1.8V at 10A and 3.3V at 3A. The device integrates a 550kHz fixed switching frequency and supports a wide operating temperature range of -40°C to 125°C. Packaged in a 24-lead SSOP, it provides efficient DC-to-DC conversion with load regulation of 0.1% and an operating supply current of 2.2mA.

DC DC Switching Controllers Feature Summary

• Dual-channel synchronous buck topology for independent output regulation
• Integrated 550kHz fixed-frequency oscillator for compact design
• Wide input voltage range supporting standard logic supplies
• High thermal performance rated for extended industrial temperatures

DC DC Switching Controllers Applications

• Multi-rail power distribution in embedded systems
• Point-of-load regulation for digital logic circuits
• Industrial control board power management
• Telecommunications equipment voltage generation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix IGN#TRPBF against the official Analog Devices datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 24-lead SSOP format. Cross-reference lot codes and material declarations if RoHS compliance or specific manufacturing origin requirements are mandated for the final assembly process.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated buck rails are required from a single intermediate bus voltage. It is suitable for designs needing high efficiency at moderate currents without external gate drivers. Compare against single-channel controllers if only one rail is necessary to optimize cost and board space. Verify that the 550kHz frequency aligns with EMI constraints and inductor size limitations.

DC DC Switching Controllers Part Context

This part belongs to the LTC1702 family of dual synchronous buck controllers designed for high-efficiency power conversion. It complements other PMIC solutions by offering integrated control for two channels, reducing component count compared to discrete controller implementations. The series is widely used in applications requiring stable voltage rails for microprocessors and memory modules.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include LTC1702CGN#TRPBF and LTC1702ACGN#TRPBF, which share the same functional architecture but may differ in electrical grade or temperature rating. Evaluate pinout compatibility and thermal characteristics before substitution.
