LT1765ES8 Description

Short technical summary and product information.

The LT1765ES8 is a monolithic buck switching regulator designed for high efficiency and fast transient response. It integrates a 3A, 0.09Ω switch along with control circuitry for current mode switching regulation.

 

This regulator operates from a wide input voltage range of 3V to 25V. Key electrical specifications include a constant switching frequency of 1.25MHz, a typical operating supply current of 1mA, and a low shutdown current of 15μA. It also features a 1.2V feedback reference voltage.

 

The LT1765ES8 is available in an 8-lead SO package and is designed for surface mount applications. Its high frequency operation allows for the use of small, low-profile surface mount components, making it suitable for space-constrained designs.

 

Applications for the LT1765ES8 include DSL modems, portable computers, regulated wall adapters, battery-powered systems, and distributed power supplies.
