LT7170RV-1#TRMPBF

Overview

The LT7170RV-1#TRMPBF is a synchronous buck switching regulator IC from Analog Devices Inc., housed in a 30-LQFN (3.5x4 mm) package. It supports an input voltage range of 2.9 V to 16 V and delivers up to 20 A output current. The adjustable output voltage spans from 400 mV to 5.5 V. Operating frequencies are programmable between 400 kHz and 4 MHz. The device features Silent Switcher technology for low electromagnetic interference, operates within a junction temperature range of -40°C to +150°C, and includes integrated shutdown functionality.

Feature Summary

• Silent Switcher architecture minimizes radiated electromagnetic interference emissions without requiring external shielding or complex layout techniques.
• Integrated synchronous rectification provides high efficiency across the load range while supporting single-phase or dual-phase operation modes.
• Programmable switching frequency allows optimization for either component size or dynamic response performance based on application requirements.

Applications

• Industrial distributed power systems
• Telecommunications infrastructure equipment
• Point-of-load regulation for processors and FPGAs

Procurement Notes

Verify the specific suffix #TRMPBF confirms the tape-and-reel packaging format with a standard quantity of 500 units per reel. Confirm RoHS compliance status and moisture sensitivity level classification prior to assembly planning. Ensure the ordering part number matches the exact electrical specifications required for the target design implementation.

Selection Notes

Select this component when designing systems requiring high current density in a compact footprint. The wide input voltage range accommodates various bus architectures. Consider thermal management strategies due to the high current capability within the small LQFN package. Verify that the chosen switching frequency aligns with available passive component values and EMI constraints.

Part Context

This part belongs to the LT7170 family of Silent Switcher regulators. It shares architectural similarities with the LT7171 but differs in specific pinout configurations and feature sets. The RV-1 designation indicates the specific package variant and internal configuration optimized for high-current applications.

Replacement Considerations

LT7170RV-1#TRPBF is a verified alternative offering identical electrical characteristics in a different packaging format.
