LT1170HVCT#06PBF

Overview

The LT1170HVCT#PBF is a monolithic high-power switching regulator from Analog Devices Inc. It operates with an input voltage range of 3 V to 60 V and provides an adjustable output voltage from 1.244 V to 40 V. The device supports a maximum output current of 5 A, delivering up to 100 W of output power. It functions at a fixed switching frequency of 100 kHz. The component is housed in a 5-pin TO-220 package with a tab for thermal management.

Feature Summary

• Supports multiple standard switching configurations including buck, boost, flyback, forward, inverting, and Cuk topologies.
• Integrates a high-current, high-efficiency internal switch along with oscillator, control, and protection circuitry on the die.

Applications

• 5V/5A Boost Converter
• 5V/5A High Efficiency Buck Converter
• -12V/5A Positive-to-Negative Buck-Boost Converter
• 5A Driving High Voltage FET for Off-Line Applications

Procurement Notes

Verify the specific suffix against official documentation, as the provided model includes a #06 suffix which may indicate a variant or packaging difference compared to the standard #PBF designation. Confirm availability status directly with the manufacturer or authorized distributors, as supply constraints may apply to this series. Ensure the procurement channel provides valid traceability and authenticity guarantees for Analog Devices components.

Selection Notes

Select this component when designing circuits requiring a versatile single-chip solution for various DC-DC conversion topologies. It is suitable for applications demanding high input voltages up to 60 V and substantial output currents. Consider the TO-220 package for through-hole mounting and adequate heat dissipation without external heatsinks in moderate load scenarios.

Part Context

The LT1170 series represents a family of high-efficiency switching regulators designed for robust performance in diverse power management applications. The HV variant specifically accommodates higher input voltage ranges, making it distinct from lower-voltage counterparts within the same product line. This integration reduces the component count required for complex power supply designs.
