Part Number: UCC2897A Other Parts Discussed in Thread: PMP9720 , Tool/software: Hi sir,
I want use the Active clamping used in PMP9720 reference design in developing an AC-DC converter.
Does this type of active clamping is Compatible to be used in AC-DC…
Part Number: PMP9720 Hi Team,
Customer is following our PMP9720 ref design, but they are not able to purchase the transformer T1(RA7040-AL) and T2(CST2-100L).
https://www.ti.com/tool/PMP9720
Please help to advise the transformer requirements for T1 and…
Terry,
The specifications of RA7040 and PH0805 are different. The number of turns from primary to secondary are different and the primary inductance is different (see below). I recommend ordering RA7040 to follow the PMP9720 reference design.
RA7040-AL…
Part Number: PMP9720 Hello,
From the latest schematics: tidrak8
I can appreciate that D10 and C33 provides a 'voltage ramp' when VOUT is starting, for a sort start (or current limit) feature.
I'd like to better understand the details around the…
Part Number: PMP9720 Other Parts Discussed in Thread: UCC27511 , UCC2897A , CSD18532Q5B Hi team,
We are using UCC2897A as ACF controller and PMP9720 as our circuit model. However, the Aux winding voltage dropped under controller working voltage Vcc cause…
Hi Aaron,
Our previous design is reference PMP7451. New project need 12V 150~200W output solution.
PMP3162 , PMP9720 and PMP9656 are all use UCC27511DBV gate driver.
But the delivery date of UCC27511 is not good, do you have any other suggested part?
Thanks…
Part Number: UCC2897A Other Parts Discussed in Thread: PMP9720 Hi TI experts,
For PMP6547_REVB reference design, what's the turn ratio of the transformer?
For wide input range, the secondary FET is having high stress, if still go with self-driven, any…
Hi Stanley,
The transformer turns ratio is determined from the ratio of VIN to VOUT. In some case the SRs are driven directly from the main secondary winding or an auxiliary secondary winding capable of providing adequate drive voltage over the entire…
