Hi,
I am having problem starting the power supply with a resistive load. The power starts fine with an active load.
What maximum capacitor can I use at Soft start pin of this device?
Thanks
Hi Farid and Anandhavel,
I apologize that no one has replied to your posts. Currently we do not have a SPICE model for this family. I would recommend looking at the following link: http://www.ti.com/lsds/ti/power-management/pwm-resonant-controller-products…
Other Parts Discussed in Thread: UC2825 I am designing a dc to dc converter using UC2825. The information in the data sheet does not define each pin os this IC. I need more information about this IC mainly circuits sugestions. If someone can help me send…
Part Number: UCC2808A-2EP Other Parts Discussed in Thread: UC1825 , UC2825 , UC3825 , TINA-TI , LM25037 Do you have a Spice model for the part?
If not, can UC1825 be used for simulation of the UCC2808A part or any other spice model can be used that is available…
Part Number: UC2825A Other Parts Discussed in Thread: UC2825 , UC1825 , TINA-TI Hi Team,
Our customer is looking for the Spice model of UC2825A. Upon checking the forum, I didn't find the Spice model for this device. However, the product page of UC2825…
Part Number: UC3842 Other Parts Discussed in Thread: UC2825 Hi,
Is there any current mode controller that supports up to 600V input voltage and external reference set?
Thanks,
Other Parts Discussed in Thread: UC2825 I am designing a PWM with UC2825 chip with the open loop laboratory text fixture recomended by TI in the application note. Making measurements in the chip´s pins everything seems to be OK, but there are not signals…
Part Number: UCC28230 Hello team,
My customer is considering to use UCC28230.
Is it possible to use only O1_D and O2_D and then drive the MOSFET at opposite side in the bridge?
I mean it is just like full bridge topology with UC2825.
I think it is OK…
Hi Art! Thank you for your patience! I was able to dig into this and although I wasn't able to find thermal ratings related to the UC2825A, I was able to find thermal ratings for the UC2825. Please see the image below from the UC2825 datasheet .
The…
Look at page 8. www.ti.com/lit/gpn/UC2825 . Design Example: 50W, 48V to 5V DC to DC Converter - 1.5MHz Clock Frequency
The output on the right (+) is shortened to gnd on the left Vin negative.
