The LT8645SEV-2#PBF from Analog Devices is a 65V, 8A synchronous step-down switching regulator designed with Silent Switcher architecture to minimize EMI emissions while maintaining high efficiency at high switching frequencies. This makes it suitable for noise-sensitive applications.
Key electrical specifications include a wide input voltage range of 3.4V to 65V, an output current capability of 8A, and adjustable switching frequencies from 200kHz to 2.2MHz. It offers up to 95% efficiency at 1MHz and 94% at 2MHz. The regulator features ultralow quiescent current in Burst Mode operation (2.5μA regulating 12VIN to 3.3VOUT), a fast minimum switch on-time of 40ns, and low dropout voltage of 60mV at 1A.
Packaged in a 32-lead 6mm x 4mm LQFN, the LT8645SEV-2#PBF is designed for surface mounting. It is AEC-Q100 qualified for automotive applications, making it ideal for automotive and industrial supplies, general-purpose step-down conversions, and GSM power supplies.
