TPS61165: Inrush current after LED was attached

nick lin

Part Number: TPS61165

Hi,

We are using TPS61165 as our LED driving circuit.

We observed that there is inrush current after we attached the LED Bar on V_ISO_LED+/V_ISO_LED-

this inrush current will have a chance to destroy our LED bar.

Is the inrush current reasonable?

Is there any method to eliminate the inrush current to protect our LED bar?

Thanks

Nick

Hi Nick,

Will this inrush current still exists if you disconnect the LED bar?
