The LT8645SEV#PBF is a high-performance synchronous step-down switching regulator from ADI Electronics, designed for applications requiring low EMI emissions and high efficiency. It operates with an input voltage range of 3.4V to 65V and can deliver up to 8A of output current.
This regulator utilizes the second-generation Silent Switcher 2 architecture, which integrates bypass capacitors to optimize fast current loops and reduce layout sensitivity, making it easier to achieve advertised EMI performance. It offers high efficiency, reaching up to 95% at 1MHz and 12VIN to 5VOUT, and up to 94% at 2MHz. The device features a fast minimum switch on-time of 40ns, enabling high step-down ratios even at high switching frequencies.
Key electrical characteristics include ultralow quiescent current of 2.5μA in Burst Mode operation for low standby power, and a low dropout voltage of 60mV at 1A. The switching frequency is adjustable from 200kHz to 2.2MHz and can be synchronized. Output ripple is less than 10mVP-P.
The LT8645SEV#PBF is available in a compact 32-lead, 6mm x 4mm LQFN package, suitable for surface mounting. It is designed for automotive and industrial supplies, general-purpose step-down applications, and GSM power supplies.
The input voltage range is 3.4V to 65V.
The maximum output current is 8A.
The quiescent current is 2.5μA when regulating 12VIN to 3.3VOUT in Burst Mode operation (LT8645S).
The efficiency is up to 95% at 1MHz with 12VIN to 5VOUT, and up to 94% at 2MHz with 12VIN to 5VOUT.
The LT8645SEV#PBF is supplied in a 32-lead, 6mm x 4mm LQFN package.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level is 1.
