The LT8619IMSE#PBF is a high-efficiency, high-speed synchronous monolithic step-down switching regulator from Analog Devices. It is designed for applications requiring a wide input voltage range of 3V to 60V and can deliver up to 1.2A of continuous current.
Key features include ultralow quiescent current of 6µA in Burst Mode operation, enabling high efficiency down to very low output currents with minimal output ripple (10mVP-P). The regulator supports a programmable fixed frequency from 300kHz to 2.2MHz and offers high efficiency synchronous operation, reaching up to 92% at 0.5A, 5VOUT from 12VIN. It also boasts a low dropout voltage of 360mV at 0.5A and a fast minimum switch-on time of 30ns.
The LT8619IMSE#PBF includes internal compensation and peak current mode topology for fast transient response and loop stability. It features an accurate 1V enable pin threshold for undervoltage lockout or shutdown, reducing input supply current to below 0.6µA. A Power Good flag signals when the output voltage is within ±7.5% of the programmed value.
This regulator is available in compact, thermally enhanced packages: a 16-lead MSOP and a 10-lead 3mm x 3mm DFN. It is AEC-Q100 qualified for automotive applications, making it suitable for automotive systems, commercial vehicles, and industrial power supplies.
