LT1171HVIQ#TRPBF

Overview

The LT1171HVIQ#TRPBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 60 V and supports a switch current of 2.5 A. The device features a fixed 100 kHz switching frequency and adjustable output voltage. It utilizes a TO-220-5 package for through-hole mounting. The component functions as a DC-to-DC converter with a quiescent current of 6 mA and operates within a temperature range of -40°C to +100°C.

Feature Summary

Supports multiple standard switching configurations including buck, boost, flyback, forward, inverting, and Cuk topologies.
Integrates a high-current, high-efficiency power switch on the die alongside oscillator, control, and protection circuitry.
Designed for operation across a wide input voltage range from 3 V to 60 V.

Applications

Positive buck converter applications
Negative boost regulator circuits
Positive-to-negative buck-boost converters

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the TO-220-5 through-hole package matches the target PCB footprint. Ensure the 2.5 A switch current rating meets the design requirements. Check for RoHS compliance status if required by manufacturing standards.

Selection Notes

Select this component for designs requiring versatile topology support beyond simple buck or boost conversion. The integrated high-current switch simplifies thermal management compared to discrete solutions. Consider the 100 kHz frequency for balancing efficiency and passive component size. Verify that the 60 V maximum input voltage aligns with the system supply rails.

Part Context

This part belongs to the LT1171 series of monolithic high-power switching regulators. The series is characterized by its ability to operate in all standard switching configurations using a single chip. The HVIQ designation typically denotes specific performance grades or package variations within the broader LT1171 family offered by Analog Devices.
