LT1076HVIR#PBF

Overview

The LT1076HVIR#PBF is a monolithic bipolar switching regulator manufactured by Analog Devices Inc. It integrates the power switch, oscillator, control circuitry, and current limit components on a single chip. The device supports Buck, Boost, and Flyback topologies with an adjustable output voltage ranging from 2.5V to 35V. It operates with an input voltage between 8V and 64V and provides a switch current of 2A. The unit utilizes a TO-220-5 package for through-hole mounting and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates power switch, oscillator, and control circuitry on a single chip
• Supports multiple topologies including Buck, Boost, and Flyback
• Includes internal current limit components for protection

Applications

• Tapped-inductor buck converter circuits
