LT1071IT#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1071IT#PBF is a monolithic high-efficiency switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3 V to 40 V and provides an adjustable output voltage with a maximum switch current of 2.5 A. The device features a fixed switching frequency of 40 kHz and a typical quiescent current of 6 mA. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and Inverting configurations. The component is housed in a TO-220-5 package designed for through-hole mounting and functions reliably across a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical ratings. Ensure the TO-220-5 package variant matches the thermal management requirements of the target application. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and compliance certifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring a single-chip solution for multiple standard switching topologies. It is suitable for applications needing up to 2.5 A output current from a 3 V to 40 V input range. Consider the TO-220-5 package for through-hole assembly needs and evaluate thermal dissipation capabilities given the integrated switch design.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1071 belongs to a family of high-power switching regulators that integrate the power switch and control logic into a single die. This integration simplifies design by reducing external component count compared to discrete solutions. The IT#PBF designation indicates the industrial temperature grade and lead-free packaging compliant with RoHS standards.
