The LT3640EUFD#PBF is a dual channel, current mode monolithic buck switching regulator manufactured by Analog Devices. It features a high voltage buck regulator with a 4V to 35V operating range and 1.3A output current, and a low voltage synchronous buck regulator with a 2.5V to 5.5V input voltage range and 1.1A output current. Both regulators can be synchronized to an adjustable frequency ranging from 350kHz to 2.5MHz.
This device includes programmable power-on reset and watchdog timers, enhancing system reliability. It operates efficiently with a typical quiescent current of 290µA and low shutdown current. The LT3640 is available in thermally enhanced 28-lead QFN and 28-lead TSSOP packages, suitable for various board space constraints.
Key electrical characteristics include a wide input voltage range for the high voltage regulator and a synchronous input for the low voltage regulator. The adjustable switching frequency allows for optimization of efficiency and component size. Its monolithic construction simplifies design and reduces component count.
