I designed the circuit of the LTC3896 by the Figure 16. High Efficiency 35V – 72V to –48V/2A Inverting Regulator in the datasheet.
But, the IC can not output the -12V.
Here is the circuit, can you give me some suggest. Thanks a lot.
What do you mean the IC can not output the -12V? Is it unstable? not regulating? Does nothing at all? Try changing your Inductor to 4.7uH.
Hi,I find out my circuit is right, but my colleague didn't layout the print circuit board according to my circuit.
Thanks a lot.
I am sorry to disturb you again. My circuit only work well once, I check the circuit.THE DRVCC is 10V, The INTVCC is 5V, but the output of IC is 0V. What should I do Next?
There is LTspice and LTpowerCAD design tools that you can use to optimize your design from the product page.
