Part Number: LM4040-N
I am trying to use the LM4040BIM3-2.5 to generate dual polar power supply similar to the circuit described in TIDA-00445, and the circuit I am doing is shown below.
The output from U10 is 24V, I am testing D10 and D11 under no load condition. Now the positive output is 2.62V and the negative output is -2.24V. Could anyone tell me if there is anything wrong with the circuit?
Plus, 2.62V and -2.24V are the two measurements if the connection of my probe is reversed, i.e., if I have +probe to 2V5P and -probe to GND, it is 2.62V, while having -probe to 2V5P and +probe to GND, it is -2.24V. Could anyone give me some ideas on what should I do for a correct output voltages?
