The LT8640SEV#PBF by ADI Electronics is a high-performance synchronous step-down switching regulator. It utilizes the second-generation Silent Switcher 2 architecture, designed to significantly reduce EMI emissions while maintaining high efficiency across a wide range of operating frequencies. This design is ideal for noise-sensitive applications and environments where electromagnetic interference is a concern.
Key electrical specifications include a wide input voltage range from 3.4V to 42V and a maximum continuous output current of 6A, with a peak current capability of 7A. The device boasts ultralow quiescent current in Burst Mode operation, drawing only 2.5µA when regulating 12VIN to 3.3VOUT. Its peak current mode control enables high step-down ratios, supported by a fast minimum switch on-time of 30ns. Efficiency is notably high, reaching up to 96% at 1MHz and 95% at 2MHz with a 12VIN to 5VOUT configuration.
The LT8640SEV#PBF is housed in a compact 24-lead, 4mm x 4mm LQFN package. Its design incorporates internal bypass capacitors to optimize fast current loops, reducing layout sensitivity and simplifying EMI compliance. The regulator operates at high switching frequencies, adjustable from 200kHz to 3MHz, and offers features like external compensation for current sharing and fast transient response in the LT8643S variant. The operating temperature range extends up to 150°C, making it suitable for demanding applications.
