ADI LT3958EUHE

升压，升压/降压升压，Cuk，反激，SEPIC5V80V3.3A（开关）

Overview

The LT3958EUHE is a wide input range, current mode, DC/DC converter which is capable of generating either positive or negative output voltages. It can be configured as either a boost, flyback, SEPIC or inverting converter. It features an internal low side N-channel power MOSFET rated for 84V at 3.3A and driven from an internal regulated 7.2V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages.

The LT3958EUHE features soft-start and frequency foldback functions to limit inductor current during start-up.
