Hi CT, Yes, all of these ICs are CCM PWM controllers. VFO mode is an optional mode for TPS23751 & TPS23752, only. If VFO mode is not used on the TPS23751 or TPS23752, All of these ICs (included TPS23756) will switch at fixed frequency at light load. They…
Part Number: TPS2372 Other Parts Discussed in Thread: TPS2373 , , TPS23752 Hi Darwin,
In general, a PD can meet MPS by supplying at least 0.5W to the PSE (usually meets the MPS spec by the load going into normal operation).
We have one family of…
Gary,
The TPS23753A is limited to Type 1, Class 3, maximum support. It was released before the IEEE 802.3at standard was released and can, therefore, not recognize the Type 2, Class 4, finger.
For a list of our Class 4 supported PDs, please utilize…
Hello,
Thank you for your question.
On a high level, due to the single gate drive, TPS23751 & TPS23752 are meant for Flyback only. TPS23752 has additional pin to support Green Mode. The TPS23754 & TPS23756 have 2 gate drives allowing for active clamp…
Other Parts Discussed in Thread: TPS23752
Table 1 shows the load power classification characters of TPS23752, my question is if the TPS23752 supply a classD amplifier with output power changes from 0 to 25W and the RCLS is used with 643.4…
Hello Mark,
That is correct the TPS23753A is a Type 1 PD so the Maximum power is 13W. The TPS23753A came on the market when the IEEE802.3.at standard was available, so the table is an .at standard table. That is why there is a note in the Class…
Hello Takahashi-san, I could not find an example of soft-start used specifically with the UCC28742, but I did find this reference involving the TPS23752: www.tij.co.jp/.../61-JAJSEO4E The soft-start circuit implementation for the TL431 shown here is identical…
Charles,
The TPS23753A is a Type 1 limited (Class 3 maximum) PD controller. If looking for a Class 4 PD (that is also known as TYPE 2), I recommend the customer consider the TPS23751, TPS23752, TPS23754, or TPS23756 solutions. You can help guide them…
I referred couple of ti design using TPS23751 ,example : 5V/4.5A(TPS23751EVM)
Input range 42.5V to 57V and Adapter range 21V to 57V
Another Ti design using TPS23751 ex: PMP8812 reference design(12V/2.1A) with same input voltage range.
when compared…
Hello Chen. It is nice to hear from you again.
If your customer requires the deep sleep mode feature, the TPS23752 is the best cross reference solution. A good reference design to share in that case, in order to get more detailed feedback from the…
