My customer now use TPS92525-EVM to test.
The Vin is 12V and output is 2.08V with about 100mA camera load.
Customer removed the R14 resistor on the EVM board and connected it to the PWM control terminal of the camera.
The camera PWM control frequency is 30hz.There will be a small chirping sound at the EVM's inductor.
When the output is PWM mode, There will be a small chirping sound at the EVM's inductor.
But when in always high voltage level mode, there is no sound at tht inductor.
Is the chirping sound normal? why will it have sound?
