Hi Team,
customer now use TPS552882 in their design and the PCB already finished. But because TPS552882 is out of stock, customer could only buy TPS55288 and add 55288 into 552882 layout.
When using TPS552882 in this board, it could work.
But when using TPS55288 in this board, it have no output.
Vin is 9-36V, output is 12V 4A. When change 552882 to 55288, do customer need to change other thing to make it have output?
Hi Amelie,
TPS55288 has I2C interface and the FB bit should be set to 04h to enable external resistor divider.
