Low Capacitance ESD/Surge Protection for Gigabit Ethernet Interfaces

Low Capacitance TVS Protection

The SY21401 is a current mode DC/DC controller targeted for Boost, SEPIC, Flyback and Forward applications. The SY21401 has an accurate DC input current limit. External compensation provides flexible adjustment of control loops for different applications. The internal low side driver is capable of sourcing 1.5A and sinking 3A current.

The SY21412A is a current mode DC/DC controller targeted for both boost and SEPIC applications. SY21412A has accurate output current limit. External compensation provides flexible adjustment of control loops for different applications. The internal low side driver is capable of sourcing 1.5A and sinking 3A current.
