Hi, all,
Would anyone be able to advice the disadvantages of using a too small sense resistor in a DCDC power supply? Or any useful online reading?
I was using a reference circuit from LT as below,
http://cds.linear.com/docs/en/demo-board-schematic/1317ahsch.pdf
Everything remains almost the same except the sense resistor RCS1 was reduced to 3mOhm instead of 5mOhm.
Recently there are some field returns that having the output 2.2uF/100V ceramic capacitors (i was using 4 per) burnt.
I am not sure whether this reduce of value will result in a poor load regulation.
Could anyone shed some light on this?
Thanks.
