Part Number: UCC28710 Other Parts Discussed in Thread: PMP4378 , TIDA-00618
I am using the UCC28710 to design a flyback circuit with multiple outputs and there are several questions that confuse me.(The designed circuit is shown in Figure).
Part Number: UCC28710 Hello,
According to the datasheet of UCC2871x, the start-up voltage on the VDD pin (VDDon) is 21V TYP and the current comes from the HV pin.
In my understanding, the HV pin needs at least 21V or more for charging the VDD capacitor…
Part Number: UCC28710 Hello All,
I'm working on a multiple output offline flyback converter using UCC28710, for the following specifications :
- Output 1 : 16 V / 50mA
- Output 2 : 16V / 50mA
- Output 3 : 15V / 1A
Using the following transformer…
Part Number: UCC28710 Hi,
I'd like to simulate a Flyback circuit using UCC28710 in LTspice. For that I need a unencryted pspice model. Can i receive the unencrypted version for simulating purposes?
With kind regards,
Part Number: UCC28710 We wondering to know if UCC28710 HV pin could work with DC voltage of the 900V,max by external resistor divider for HV pin? Please find below diagram.
If it's not suited solution, what solution you can recommend? thanks.
Part Number: UCC28710 Hello:
An interesting question: how would one measure traditional " frequency response" to get Gain-Margin & Phase-Margin?
If you add too many extra components to create a Test circuit, then FRA will be their response…
Part Number: UCC28710 Other Parts Discussed in Thread: PMP10319 Hi team, My customer plan to design with reference to PMP10319. https://www.tij.co.jp/tool/jp/PMP10319 But, I couldn't find a way to calculate L2 in the below schematic. Could you tell me…
Part Number: UCC28710 Hello Ulrich:
Intriguing issue: while running a module with UCC28710D, using a convenient 650v GaN device ( from Transphorm, same $), with only 10W operation- but has 2 outputs thnx to very tightly controlled transformer( lkg ~1uH…
Part Number: UCC28710 Hi Team,
a customer ran into an issue with the PSpice model of UCC28710.
He is using PSpice and got the following error message:
ERROR(ORPSIM-15108): Subcircuit UCC28710 used by X_U6 is undefined
Would you know what causes this issue…
