Other Parts Discussed in Thread: TPS2546
Hi Team,
My customer's application is purely using DCP mode and they could not achieve fast charging on the 0010 CTL/ILIM_SEL (DCP_Auto) settings, the best they could achieved is only about 500mA.
They also tried the DCP_Force mode setting, the CTL setting highlighted below. With this mode they can only get less than 300mA only. they tried it with Android and Iphone mobile phone. but surprisingly when they use COTS charger, they can get more than 1.8A using the same mobile device that they're using.
In general, they already tried all the DCP_Auto mode and DCP_Force but they could not get current higher than 500mA.
My customer is now thinking to bypass the TPS2546 chip if possible, please confirm if this is ok? their design is purely for charging purposes only, they don’t need the data thru.
Below is some of the test result:
Using TI EVK TPS2546 Evaluation Board.
Using GP, COTS Charger
Using CTD-050300A, COTS charger.
Your feedback is much appreciated.
Best Regards,
Ernest
