LT7170RV-1#TRPBF

Overview

The LT7170RV-1#TRPBF is a monolithic synchronous buck converter from Analog Devices, designed for high-current applications. It integrates power switches and control circuitry to deliver up to 20A of output current. The device supports single or dual-phase operation with an input voltage range of 3V to 16V. It features a programmable switching frequency between 400kHz and 4MHz, allowing optimization for efficiency or size. The output voltage is adjustable down to 0.4V. Packaged in a compact 30-lead LQFN (3.5x4mm) suitable for surface mount assembly, it operates over a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates high-side and low-side power switches for efficient synchronous rectification
• Supports configurable single-phase or dual-phase parallel operation for increased current capability
• Features Silent Switcher architecture to minimize radiated electromagnetic interference without external snubbers
• Includes programmable soft-start and tracking capabilities for controlled power-up sequences

Applications

• Point-of-load regulation for industrial equipment
• Power distribution systems in telecommunications infrastructure
• High-density computing and server power supplies
• Automotive electronics requiring robust thermal performance

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the RV-1 variant matches the required pinout and electrical specifications for your design. Cross-reference the manufacturer datasheet for latest revision notes and recommended component values. Ensure supply chain sources are authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when designing systems requiring up to 20A from a 16V input source. Consider dual-phase configuration if thermal management or ripple reduction is critical. Evaluate the switching frequency setting against inductor size constraints and EMI requirements. Verify that the 30-lead LQFN package fits within the available PCB area and thermal pad requirements.

Part Context

This part belongs to the LT7170 family of Silent Switcher regulators. It shares architectural similarities with other members like the LT7171 but differs in specific integration levels and phase options. The family targets high-efficiency, low-noise DC-DC conversion needs where space and electromagnetic compatibility are primary design drivers.

Replacement Considerations

LT7171RV-1#TRMPBF offers similar functionality with potential differences in internal switch resistance or control loop characteristics.
