LT1765EFE-5 Description

Short technical summary and product information.

The LT1765EFE-5 is a 1.25MHz monolithic buck switching regulator from Analog Devices. It features a high efficiency 3A, 0.09Ω switch integrated on the die, along with control circuitry for a high frequency, current mode switching regulator. Current mode control ensures fast transient response and excellent loop stability.

 

This regulator operates over a wide voltage range of 3V to 25V and includes a 1.2V feedback reference voltage. It is available in a thermally enhanced 16-lead TSSOP or an 8-lead SO package, both suitable for surface mount applications. The device offers a low shutdown current of 15μA, reducing power consumption when not in active use. Its high frequency operation allows for smaller input and output filtering components, enabling the use of chip inductors.

 

Applications for the LT1765EFE-5 include DSL modems, portable computers, regulated wall adapters, and battery-powered systems. It provides full cycle-by-cycle current control and thermal shutdown for protection. The switching frequency can be synchronized to an external signal up to 2MHz.
