LT1072IN8#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1072IN8#PBF is a monolithic high-efficiency switching voltage regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3 V to 60 V and delivers a switch current of 1.25 A. The device features an adjustable output voltage with a minimum fixed level of 1.25 V and maintains a low quiescent current of 6 mA. Operating at a switching frequency of 40 kHz, it supports multiple topologies including buck, boost, Cuk, flyback, forward, and inverting configurations. The component is housed in an 8-pin PDIP package designed for through-hole mounting and functions reliably across a temperature range of -40 °C to +125 °C.
