Part Number:TPS2561
Dear All,
We are using TPS2561 on one of our USB charging product along with TPS2513 DCP chip. As per datasheet 2.8A can be load per independent channel. Hope we can use independent channel for individual 2A load.
But observed USB load on on channel/ OUT1, shows loading on 2nd channel / OUT2 ( even though nothing is connected on OUT2 port) & Vice versa
Example: 1.5A of USB resistive load on channel1 /Out1 shows output voltage of 4.772V with input supply of 5.2V ( Later I wl increase input voltage to 5.5V n check), but why Channel 2 / OUT2 output voltage is loading to 4.685V without connecting any load on OUT2 port? & Vice versa
Kindly note: Current limit resistor (ILIM) used as 28Kohm as per datasheet for 2A load.
Can somebody provide valuable feedback on this issue
Thanks & Rgds
