I am using STWBC2-HP and STWLC99 for development. The output voltage at the receiver end is set to 10V, and the current limit at the transmitter end is set to 5A. However, the actual current at the transmitter end can only reach a maximum of 0.8A, and I do not know why.

Hello,

ST has decided to limit its offer in terms of power (30W) and in terms of portfolio.

We focus now on 4 products : the STWBC86 (up to 5W) + the STWBC2-HP (up to >30W) for Transmitter side and the STWLC38 (up to 15W) + the STWLC89 (up to 20W, Qi 2.0 MPP) for Rx.

Unfortunately, the STWLC99 has been stopped.

Although your STWLC99 has been discontinued, I have already purchased ST's products, and I should receive the support I am entitled to. The issue I am facing now is that the output current of the STWBC20-HP can only reach 0.8A. I need to resolve the problem on the transmitter side, not the STWLC99.
