LT1170CQ#TRPBF

Overview

The LT1170CQ#TRPBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 60V and provides an adjustable output voltage starting from 1.244V. The device supports a maximum switch current of 5A and functions at a fixed switching frequency of 100kHz. It is housed in a TO-263-6 (D2PAK) package with five leads and a tab, suitable for surface-mount installation. The component is rated for operation within a junction temperature range of -40°C to 100°C.

Feature Summary

Supports multiple standard switching topologies including buck, boost, flyback, forward, inverting, and Cuk configurations
Integrates a high-current, high-efficiency power switch on the die
Includes complete oscillator, control, and protection circuitry

Applications

Buck converter designs
Boost converter designs
Flyback converter applications
Forward converter implementations
Inverting regulator circuits

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the CQ grade matches the required operating temperature range of -40°C to 100°C. Ensure the D2PAK footprint aligns with the PCB layout specifications. Cross-reference the manufacturer part number directly with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component for applications requiring versatile topology support and high current handling up to 5A. The integrated switch eliminates external MOSFET requirements, simplifying design. Consider the 100kHz switching frequency for balancing efficiency and component size. Verify that the 60V maximum input voltage meets system requirements.

Part Context

This part belongs to the LT1170 family of monolithic high-power switching regulators. The family is characterized by its ability to operate in all standard switching configurations. Variants within the series share core functionality but differ in temperature grades and packaging options such as CT or IQ suffixes.
