Part Number: UCC28911 Other Parts Discussed in Thread: UCC28730 , UCC28910 Dear TI Team
Our customers are looking for reference designs and devices that meet the following conditions: ・ AC85 ~ 264V input ・ 5V 0.5A output ・ Non-insulated type
I searched…
Hi,
Please use the configuration in figure 5. This help input voltage to be sensed without the influence of output voltage.
During the ON time of MOSFET the current will be injected out of the Vs pin and this will provide a measure of the input voltage…
Hi Yunsheng
Thank you for your reply.
I understand that PMP20686 is closest to our customer's spec.
I also considered a circuit configuration that meets the following specifications, but I would like to know about PMP22557 again.
If the PMP22557…
Part Number: UCC28910 Other Parts Discussed in Thread: PMP , UCC28881 Hi,
It is my first SMPS implementation. Im using UCC28910 to implement a 5V/200mA non isolated power supply based in http://www.ti.com/tool/PMP4443 and http://www.ti.com/lit/an/snva750…
Hi Michelle,
There are two other parts that you may consider for your application: UCC28910 and UCC28911. These can be configured into a non-isolated high-side buck topology similar to that of the UCC28880/1, with some layout change.
Here are links…
