LT3579IFE#PBF

LT3579IFE#PBF Description

The LT3579IFE#PBF from Analog Devices Inc. is a highly versatile DC switching voltage regulator designed for demanding power management applications. This adjustable-output regulator supports a wide input voltage range (2.5V to 16V) and delivers up to 6A of switch current, making it ideal for both step-up (boost) and step-down (buck) configurations. With a switching frequency range of 200kHz to 2.5MHz, it offers flexibility in balancing efficiency and component size. The device features a positive or negative output configuration, enabling it to generate outputs from 1.215V up to 42V (switch-dependent). Packaged in a 20-pin TSSOP tube, it is RoHS3 compliant and suitable for surface-mount applications.
