LT1172MJ8 Description

Short technical summary and product information.

The LT1172MJ8 is a monolithic high-power switching regulator from Analog Devices, designed for high efficiency operation. It can be configured in various switching topologies including buck, boost, flyback, forward, inverting, and Cuk.

 

Key electrical specifications include an internal 1.25A switch, an input voltage range of 3V to 60V, and a switching frequency of 100kHz. It also features a low quiescent current of 6mA and a shutdown mode that draws only 50µA. The device offers adjustable output and can be configured for positive or negative output voltages.

 

This regulator is suitable for applications requiring up to 100W of load power without external power devices. It is self-protected against overloads and operates in a wide temperature range from -55°C to 125°C.

 

The LT1172MJ8 is supplied in an 8-CERDIP package and supports through-hole mounting.
