LT8645SIV#PBF Description

Short technical summary and product information.

The LT8645SIV#PBF from Analog Devices is a high-performance synchronous step-down switching regulator. It is designed for applications requiring efficient power conversion with a wide input voltage range, from 3.4V to 65V, and capable of delivering up to 8A of output current.

 

This regulator utilizes a Silent Switcher 2 architecture, minimizing EMI emissions and reducing layout sensitivity. It operates with a switching frequency adjustable from 200kHz to 2.2MHz, allowing for optimized solution size and efficiency. Key electrical specifications include a low quiescent current of 2.5µA in Burst Mode operation and a fast minimum switch on-time of 40ns, enabling high step-down ratios.

 

The LT8645SIV#PBF is housed in a 32-lead LQFN package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ), making it suitable for various industrial environments. The output is adjustable and configured as positive.

 

This component is designed for applications such as automotive and industrial supplies, and general-purpose step-down conversion where high efficiency and low EMI are critical.
