Hello, Team!
My customer have question as shown below for TPS2373-4.
1. Is it possible to configure the VC_IN as a voltage distribution using resistors on the primary side instead of the AUX bias supply as in the circuit diagram below?
(In case of the same configuration as the application circuit, there does not maintain the voltage because of the auxiliary winding output delay until the PWM IC operates after classification operation.)
2. MPS_Duty was indicated on the datasheet according to specifications such as C (bulk), Bridge Diode, etc.
If the C (bulk) is larger than the datasheet specification or the MPS_Duty operation is not normally performed due to the characteristics of the diode, can the PSE power supply be cut off due to the failure to maintain the minimum current?
3. If the C (bulk) capacity is large, the Inrush Current time may be long. At this time, can the TPS2373-4 internal Hotswap MOSFET be damaged and cause problems? (C(bulk) was applied 440uF.)
