Other Parts Discussed in Thread: LM3150
Hello E2E,
I tried VOP operation for LM3150 on EVM.
www.ti.com/.../LM3150-250EVAL
I applied a bias of 0.8 V to the FB port. The LM3150 has stopped operating. Please see the attached file.
The datasheet says that " Once the overvoltage protection is activated, the HG and LG signals remain off until the voltage at FB pin falls below 0.72 V.".
In other words, I think that "It recovers when the voltage at the FB pin falls below 0.72V.". Is my idea corect?
And, when stopped by OVP, stopping time is about 13msec.
Is it normarly?
Regards,
ACGUY
