  • Description

    The LTC3891IFE#PBF is a DC DC switching controller used for driving 6V-rated MOSFETs in high voltage applications. It is optimized for both low and high power applications and requires only a few components to provide a complete power supply solution. The switching frequency can be adjusted from 50kHz to 1MHz using an external resistor or synchronized to an external clock.
