TPS2412D General Description

The TPS2412/13 controller, in conjunction with an external N-channel MOSFET, emulates the function of a low forward voltage diode. The TPS2412/13 can be used to combine multiple power supplies to a common bus in an N+1 configuration, or to combine redundant input power buses. The TPS2412 provides a linear turnon control while the TPS2413 has an on/off control method.

Applications for the TPS2412/13 include a wide range of systems including servers and telecom. These applications often have either N+1 redundant power supplies, redundant power buses, or both. Redundant power sources must have the equivalent of a diode OR to prevent reverse current during faults and hotplug. A TPS2412/13 and N-channel MOSFET provide this function with less power loss than a schottky diode.

Accurate voltage sensing and a programmable turnoff threshold allows operation to be tailored for a wide range of implementations and bus characteristics. The TPS2412/13 are lower pin count, reduced feature versions of the TPS2410/11.

Leds norms, the price is lower than those of competitors, filed 3.3 v 200 mah keep perfectly, the shade is closer to warm.

Ordered on march 6, put in the mailbox on april 22. The product corresponds to the description.

The parcel was horror for how long! More than 5 days to moscow. But, after all, i got, for this the seller thanks.The parcel was put in the mailbox.

In principle, it works, increases. All 5 pcs that ordered. However, no 2a can be said. With an increase from 3.7 v to 5.2 v at the input to 1a work stably-at the output current 0,4-0,5 a. Then how lucky.
