The LT8640EUDC#PBF from Analog Devices is a high-performance synchronous step-down switching regulator designed for efficiency and low EMI emissions. It operates with an input voltage range of 3.4V to 42V and can deliver up to 5A of continuous output current, with a peak transient output of 7A.
This regulator boasts an ultralow quiescent current of 2.5µA when the output is in full regulation, making it suitable for applications requiring high efficiency at very small load currents. Its Silent Switcher architecture minimizes electromagnetic interference (EMI), while supporting high switching frequencies up to 3MHz. The device offers a fast minimum switch on-time of 30ns, enabling high VIN to low VOUT conversions at high frequencies.
The LT8640EUDC#PBF is available in a compact 18-lead 3mm x 4mm QFN package, suitable for surface-mount (SMD/SMT) applications. It operates within a temperature range of -40°C to +125°C. The device supports adjustable and synchronizable operation from 200kHz to 3MHz, with an output voltage range of 0.97V to 41.9V.
The maximum input voltage is 42V.
The maximum continuous output current is 5A.
The quiescent current is 2.5µA when the output is in full regulation.
The switching frequency is adjustable from 200kHz to 3MHz.
It is supplied in an 18-lead QFN package.
The operating temperature range is -40°C to +125°C.
