DC-DC Solution for 10V to -13V


I am looking for a DC-DC Converter Solution converting 10V to -13V. Max output current should be around 1,5A. The efficiency should be optimized for Iout 600mA-800mA. Temperature range is -40 to 85°C. Enable control is required. Isolation is not required. Priority should be on efficiency and thermal performance and not on size. Could you please recommend 2 or 3 parts as a starting point.



You could use a buck as an inverting buck-boost for the negative rail. The input should be wide enough to account for your max input additional to abs value of output. Additionally, you can calculate and give some margin for output current. There should be articles online that you can refer to.
