Hi,
I am trying to design a pcb powe supply that convers 24V DC to 34V dc (for Mbus communication)
I have designed the folowing power supply as shown in the picture.
When i turn it on it just starts heating up pulling 0.5A under no load (likely shorting or something). I have thecked the pins for any short circuits but everything on the pcb seems fine.
When i remove the 0.22 R19 resistor it works strangely and only generating 6.4V.
Am i mising something from the design? What could be the cause for the shorting?
I have slightly larger coil and capacitor because the exact datasheet parts were not available.
