Part Number: TPS25810 Other Parts Discussed in Thread: TPS2561A Dears,
I am developing an USB type-C battery charger, I'd like to use TPS25810 but I need to understand if TPS25810 is compliance with IEC62680-1-1
many thanks

Eric,
The UCC28740 controller on the primary side has built-in CC-mode overload protection.
As noted on the schematic for PMP10478, the UCC28740 power stage is designed for >6 A capability.
From eqn. 3 in the UCC28740 datasheet, Rcs = (Vccr * Nps…
Frank, Are you asking if you can use the LT3525 regulator that has a supply of 40mA to drive the TPS2513A EVM? If that is what you are asking, that will not work as the EVM is still being supplied an inadequate current amount. What do you have plugged…
Part Number: TPS2561
Hi,
I'd like to seek for your advice if we could supply two different voltages to TPS2561/TPS2561-Q1/TPS2561A as per diagram below?
Thanks
Yes, this configuration is allowed and can effectively double the switch current if Rilim remains unchanged. If you refer to the TPS2561A datasheet, you can find a rating for this configuration in the EC table.
Dear Eric
Thanks for your help
May I know TPS2561A have the same issue ?
Our end customer worry about the ambient temperature will effect the result
Thanks
Hi Venkata,
Thanks for your response.
Our Power supply is also used to power up MCU circuit.
If we use TPS25942A (5V@5A) for all 3 ports similar to Solution 2 then it may cause too much load for our power supply or disable our MCU circuit when all 3 ports…

Nakai-San,
Tps2514A supports 2.4A charging. It has no power switch, if customer needs to add one, they can choose tps25200 together with tps2514A.
If customer needs dual Chanel, they can use tos2513A+tps2561A
TPS251x already integrated some internal deglitch timer avoid noise affection.
TPS2511 has power switch, but TPS2513 only is controller, need external power switch like TPS557 (single channle @ 22mohm) and TPS2561A (Dual channel @ 44mohm), both are…
