Vue d'ensemble

Description

The LT8646SEV#PBF is a high-efficiency, monolithic synchronous step-down regulator. It is designed to deliver up to 8A of continuous output current from input voltages ranging from 3.4V to 65V, making it suitable for automotive, industrial, and general-purpose applications. The device operates with a low quiescent current and features a Silent Switcher® architecture that minimizes electromagnetic interference (EMI), enabling quiet operation suitable for noise-sensitive environments.
Key features of the LT8646SEV include fast minimum on-time (as low as 40ns), which supports high step-down ratios even at high switching frequencies. The regulator also offers programmable switching frequency, spread spectrum frequency modulation, and synchronization to an external clock. It includes protection features such as short-circuit protection, thermal shutdown, and a robust 42V output transient tolerance.
The LT8646SEV is available in a thermally enhanced 4mm x 4mm LQFN package, allowing efficient thermal management. Overall, it is ideal for applications requiring high efficiency, compact size, and low noise performance.
