The LT8640SEV#PBF is a 42V, 6A Synchronous Step-Down Silent Switcher manufactured by Analog Devices featuring a low 2.5 A quiescent current. It is a switching voltage regulator designed to reduce the voltage of an input down to the output voltage in a smooth, continuous manner. This device is ideal for automotive applications due to its low quiescent current, thermal overload protection, and ruggedized design. It also has multipleenable functions including power-good indication, adjustable soft-start, and ±1% feedback accuracy. The LT8640SEV#PBF is a reliable, low-cost solution for applications with strict voltage, current, and thermal requirements.
