Other Parts Discussed in Thread: TPS2373
Hi
Test according to the following circuit diagram, the probe is connected before the rectifier bridge.
The load is two parallel 194ohm non-inductive resistors, the load power is about 30W,
the input is connected to the PoE switch network port, and the IC uses TI’s TPS2379.
The LED on the load board flashes once, but the load board does not work normally. Every time, the LED on the load board flashes once.
The previous conditions remain unchanged, one of the back loads is disconnected, that is, the load power is 15W, and the load board can work normally
Please help confirm what is causing the problem.
Thanks and regards
Rock
