Part Number: PMP10143 Other Parts Discussed in Thread: UCC28880 , UCC28911 , UCC28910 Hi,
Customer is working on a design based on PMP10143, according to them it is working very well.
However,their load is only 250mA on 3.3VDC causing a Fsw of about 4.5kHz…
Part Number: PMP10143 Hi team, Our customer is requesting for the PCB layout of PMP10143. The CAD files only contain the schematic file and no layout. Can you share this file? Thanks, Jonathan
Other Parts Discussed in Thread: PMP10143 , TL431 , UCC28880 Please let me know about mean of external components for PMP10765 and PMP10143 below.
①About noise filter, why difference capacitor value?
（PMP10765 is 1mH/6.8μH/6.8μH, but PMP10143 is 1mH/4…
Victor,
You could take a look at PMP10143:
www.ti.com/.../PMP10143
This is a 1.7 W design using UCC28880. This is a dual output, 3.3 V @ 0.4 A & 12 V @ 0.03 A.
For your requirement, you could change to the UCC28881, remove the 12 V output, and…
Matsumoto-san,
Q1 - in the buck-boost configuration as shown in Fig. 22, the Vout- is connected back to Vin+, so the DC output voltage is floating high wrt Vin-, and will move up with Vin voltage level.
E.g. if Vin = 150 Vdc, then Vout- will sit at…
