oem power supply, 31.5 vdc 1.5 A.
I want to change the output to 24 v.
There is one 8-pin IC, labeled:
230D1 PUICO
I don't see a datasheet anywhere for this.
Any ideas?
Thanks, Dave

Logo seems pretty non-descript...
Anyone recognize it?
Thanks.
It is an OnSemi PWM controller:
The board is a 5-layer. Here's the other side of the board (the LV end):
This is a ASTEC ps from a large HP inkjet printer.
It's a simple 2-resistor voltage divider on the output which determines the output voltage. I'll replace one of these with a pot -- for trials -- then a fixed R when the value is determined.
Thanks.
