Hi there,
I designed a simple boost converter board with this chip. My board boosts from 15V to 24V, the 24V is then used on optocouplers which are controlled by a beagle bone's inputs to switch the solenoid valves on and off. The board had been working fine for the past couple of weeks but all of a sudden stopped working. It could be a number of variables, one being that we switched from a benchtop power supply to a battery (this one to be exact: https://www.rrc-ps.com/fileadmin/Dokumente/Data-Sheets/DS_RRC2054.pdf ) . I was hoping to get someone that is an expert on this chip to look at my schematic and PCB layout to see if there are things that might be missing that could cause harm to the chip that I didn't think about. Thank you!
