Hi,
I am using the module to get 5.7V from an input of 20V-50V. For some reason, when I power it up, the output goes to ~21V. When I vary the input voltage from 25V - 40V, the output moves with it from 19.9v - 22.24V. When the input voltage drops below ~25V, the output stays about 3V below the input.
I tried increasing Cout to around 20uF but that didn't do much.
The schematic is shown below. I should have probably ran a test pad to PGOOD, but I thought it's a simple chip, what could go wrong.
Thanks
