I am using the LT3086 power module for the generation of 5V supply from 7V input.
I am using the current limit function in the module so I connected 1K-10nF series circuit parallelly 1K RMON resistor. So as per the calculation, the current is limited to 800mA.
with this module, I am using a digipot AD5292 to varying the SET resistor to adjust the output according to my application. In the default condition, the AD5292 is in 50K resistor and I am using 42K series resistor.
With no-load condition I am getting 5V output as per calculation. But when I connected the load around 10Ohms voltage is dropped to 3.4V. When I connected the load around 20Ohms I am getting 4.5V.
I don't know what is the issue when I connected the load
Please review my design and let me know where I am doing wrong.
