The LT8641EUDC#PBF from Analog Devices is a high-performance synchronous step-down buck switching regulator. Designed with Silent Switcher architecture, it minimizes EMI emissions while delivering high efficiency. This IC supports a wide input voltage range from 3V to 65V and can deliver up to 3.5A of continuous output current, with a peak transient output of 5A.
Key electrical specifications include an adjustable output voltage starting from 0.8V up to 64.35V. The switching frequency can be set between 210kHz and 2MHz. It operates efficiently, achieving up to 95% efficiency at 1MHz and 12VIN to 5VOUT. The device also boasts an ultralow quiescent current of 2.5µA in regulation and an output ripple below 10mVP-P.
Packaged in a compact 20-WFQFN (3x4mm) with an exposed pad, the LT8641EUDC#PBF is suitable for surface mount applications. It operates across a wide temperature range of -40°C to 125°C (TJ). Essential features include a synchronous rectifier for improved efficiency and a fast minimum switch on-time of 35ns, enabling high step-down conversion ratios at high frequencies.
