LT1171IQ Description

Short technical summary and product information.

The LT1171IQ is a monolithic high power switching regulator designed for high efficiency operation. It supports a wide input voltage range from 3V to 60V and draws only 6mA of quiescent current. The device includes an internal switch with a maximum current rating of 2.5A for the LT1171 variant.

 

This switching regulator can be operated in various configurations including buck, boost, flyback, forward, inverting, and Cuk topologies. It offers self-protection against overloads and features a shutdown mode that reduces supply current to 50mA for standby operation. The LT1171IQ is available in standard 5-pin TO-3 and TO-220 power packages, as well as 8-pin MiniDIP and surface mount packages.

 

With its integrated control and protection circuitry, the LT1171IQ simplifies design and provides robust operation. It is suitable for applications requiring efficient power conversion and regulation across a broad range of input voltages.
