After simulating the LT3462 with the recommended circuit, there were no problems, so I mounted it on the board.When the input is set to +15V DC and the output-is set to 18V,The output changes from about -19V to about -18.5V,A triangular waveform of several MHz is different in the output by about 50 mV.I am troubled because it is different from the set voltage and abnormal oscillation occurs.The pattern of the board is made similar to the recommended pattern.Is there a recommended constant for normal operation?please tell me
Hi,
there are three problems using this part for your application. 1. The input is too high. It will exceed the 16V maximum. 2. the inrush current will be exceeded for the internal diode. 3. the load current…
Your title says "How to use LT3464", and you are simulating the LT3462. Which one is it?
Please state your input voltage range, and max load current.

Dear dulcevida
I'm sorry
The correct model number is "LT3462ES6#TRMPBF".
Also, regarding your question.Input voltage range: DC+15V±10%Maximum load current: Approx. 100mA
This is the case.Best regards.

there are three problems using this part for your application. 1. The input is too high. It will exceed the 16V maximum. 2. the inrush current will be exceeded for the internal diode. 3. the load current you need is too much.
I would recommend you consider LT8330 for your application.
Best,
I will consider this with the recommendations you have answered.
Thank you very much.
Best regards.
