LT LTC1871EMS

升压，升压/降压升压，反激，SEPIC2.5V ~ 36V

Overview

The LTC1871EMS is a wide input range, current mode, boost, flyback or SEPIC controller that drives an N-channel power MOSFET and requires very few external components. Intended for low to medium power applications, it eliminates the need for a current sense resistor by utilizing the power MOSFET’s on-resistance, thereby maximizing efficiency.

The LTC1871EMS is available in the 10-lead MSOP package.
