TPS61060: Startup waveform and switching frequency data

Part Number: TPS61060

Hi...

I want to get the startup waveform and switching frequency data of TPS61060 when it is started up instead of steady state.

I think that Fsw of TPS61060 is lower than 1MHz when it is started up. Is it right?

Please let me know that and forward me related data.

Regards.

Hi Jeffrey,

The startup waveform is Figure 13 in the datasheet. I believe once it starts switching, the frequency should be the same. I will check it in the lab and update the post later today.

Hi Jeffery,

As you can see from the scope shot, After the first few irregular pulse, the switch waveform is rather constant at 1MHz.

Hi Jeffery,

Looks like I am having some problem pasting the images on this forum. Can you send me an email and I can attached the scope shot in my reply.
