The LTC3646EMSE#TRPBF is a synchronous step-down DC/DC converter manufactured by Texas Instruments. It operates with a wide input voltage range from 4.0V to 40V and can deliver a guaranteed output current of 1A. This converter boasts high efficiency, reaching up to 95%, and draws a low quiescent current of 140µA typical in Burst Mode operation.
Key features include an adjustable switching frequency between 200kHz and 3MHz, a precise 0.6V reference voltage, and selectable Burst Mode or forced continuous mode operation. The LTC3646 is available in either a 14-lead 3mm x 4mm DFN package or a thermally enhanced 16-lead MSOP package, making it suitable for various high-voltage applications.
This device is ideal for point-of-load power supplies and intermediate bus power applications. Its robust design includes internal soft-start and short-circuit protection, contributing to its suitability for demanding environments.
