LT1076IT#PBF

Overview

The LT1076IT#PBF is a monolithic bipolar switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 8V to 40V and provides a fixed 5V output. The device supports a switch current of 2A and functions at a switching frequency of 100kHz. It utilizes a TO-220-5 package for through-hole mounting and is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates power switch, oscillator, control circuitry, and current limit components on a single chip
• Supports buck, boost, and flyback topologies for versatile DC-to-DC conversion
• Capable of generating positive or negative output voltages

Applications

• Tapped-inductor buck converter circuits
• Positive-to-negative voltage conversion systems
• Industrial power supply designs requiring high efficiency

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the TO-220-5 package matches your PCB footprint requirements. Confirm RoHS compliance status for your region's regulatory needs before finalizing procurement.

Selection Notes

Select this component when a robust 2A switching regulator is needed for applications supporting both buck and boost operations. The integrated design reduces external component count compared to discrete solutions. Consider the thermal performance of the TO-220-5 package for heat dissipation in enclosed environments.

Part Context

This part belongs to the LT1076 family of switching regulators, known for their high efficiency and minimal external parts requirement. The IT variant specifies the industrial temperature grade and fixed 5V output configuration within the broader product line.
