Other Parts Discussed in Thread: LM27313
Hi,
I am using lm27313 for converting DC 12V to 24V. My initial load current will be 5mA. Is there chance of output voltage spike to 40V and come back to 24V?
Thanks.

Hi Santhosh,
Do you mean that in normal operation, the Iout is 5mA, while the load is disconnected, there is a transient big 200mA Iout?
For further check, could you provide the Cout and current load profile? Especially in the moment of load disconnected.

Hello,
In normal operation, load current is 5mA. Some time I am connecting 200mA resistive load. During disconnecting load, I am getting spike on output voltage.
Input voltage DC 12V.
Output voltage 24V.
Output capacitor 4.7uF/35V.
Input capacitor 1uF/35V.
Inductor 22uH.
Hi Santhosh,
What's the detailed process of "disconnecting load"? I mean, was the disconnection realized by a MOS or other ways? is the load pure resistive or inductive?
Could you let me know what the application is?
Thank you.
