Part Number: UC2572 Dear colleague,
Our customer wants to use UC2572 to make power solution, Vin=12V, Vout=-200V, Iout_max=1mA.
UC2572 is a very old device.
Do we have some new devices and some design?
Thanks a lot!
Best Regards,
Rock S…
Hi XiaoTao,
Thank you for your interests in UC2572. Unfortunately we do not have the TINA model for it at this moment, but the core circuit of the IC is straightforward and I think you should be able to create a model according to the IC block diagram…
Part Number: UC2572 Other Parts Discussed in Thread: LM5160 Hi,
I want to design a dual tracking power supply +-15V. I have designed this circuit for the +-15V and I have used a buck converter for the +15V. How can I achieve a proper tracking regulation…
Part Number: UC2572 Other Parts Discussed in Thread: LM5022 Hi Team, A customer wants to use the UC2572, but the switching Freq is too slow for them. Do we have a direct functional replacement (need not be pin to pin) to the device with atleast 400 KHz…
Part Number: UC2572 Hi team,
Customer want to use UC2572 to do 12V->-40V conversion.
How to calculate the Rcomp and Ccomp? Do you have a guide line for the peripheral component?
Thanks.
Robin
Part Number: UC2572 Other Parts Discussed in Thread: LM5116 Hi sir,
Do you have any design tool for UC2572?
My customer want design for a 24V to -36V schematic, but I can't find detail for how to design this schematic in datasheet.
Thanks!

Other Parts Discussed in Thread: UC2572 , LM5118 , TL5001 Hello:
Does TI have a chip like the UC2572, but at a higher frequency? _ 300KHZ or faster?
Any feedback or input is welcomed and appreciated!
Thanks again!
Paul
The input voltage is -48 V. the output voltages and currents of the various modules for the POL converters are given in the schematic and table 1. They are somewhat adjustable, but that circuit is specifically designed to support Advanced Telecommunications…
The UC2575 should be able to support your +15V to -80V application. For +15V to +10V, you can also use the UC2575. Regarding other devices, you may need to send separate post and it will be directed to the right engineers.
Other Parts Discussed in Thread: UC2572 Hello,
does anyone know how to calculate the most important parts for the (very old) UC2572.
I never saw a datasheet with so less informations.
