LTC3772EDDB Description

Short technical summary and product information.

The LTC3772EDDB is a high-performance DC/DC switching controller designed for step-down (buck) applications. Manufactured by LT, this controller operates at a constant frequency of 550 kHz, enabling efficient power conversion.

 

Key features include its No RSENSE architecture, which removes the requirement for a current sense resistor, thereby improving efficiency and saving valuable board space. It supports a wide input voltage range from 2.75V to 9.8V and can deliver an output current of up to 5A. The device also boasts a low no-load quiescent current of 0.04mA and a shutdown current of 8µA, making it suitable for power-sensitive applications.

 

The LTC3772EDDB is available in a compact 3mm x 2mm DFN-8 package, designed for surface mount installation. Its operating temperature range is from 0°C to 85°C.
