LT1765ES8#PBF Description

Short technical summary and product information.

The LT1765ES8#PBF is a high-efficiency, monolithic buck switching regulator designed by Analog Devices. It integrates a 3A, 0.09Ω switch along with control circuitry for a high-frequency, current-mode switching regulator. This design provides fast transient response and excellent loop stability.

 

The regulator operates over a wide input voltage range from 3V to 25V and maintains consistent performance. It features a constant 1.25MHz switching frequency, which allows for the use of smaller, low-profile surface mount components, including chip inductors. The device includes full cycle-by-cycle current control and thermal shutdown for protection.

 

Key electrical specifications include a 3A switch current, a 1.2V feedback reference voltage, and a low shutdown current of 15μA. The operating supply current is typically 1mA. The LT1765ES8#PBF is available in an 8-SOIC package, suitable for surface mount applications.

 

This switching regulator is suitable for various applications such as DSL modems, portable computers, regulated wall adapters, battery-powered systems, and distributed power systems. Its current mode loop control and synchronizable operation up to 2MHz offer design flexibility.
