Part Number: TPS61232 Other Parts Discussed in Thread: TLV62080 , When power off sequence for TPS61232 (and TLV62080) power line, TPS61232 and one of TLV62080 Vout are unstable.
Please let me know about the reason of unstable power down and any idea…

Other Parts Discussed in Thread: TLV62080 , TLV62080EVM-756 Hi sir, May I know TLV62080 phase margin at 100% duty result show as FIG is right? because no cross frequency.
test condition :
Vin 3.3V, Vout 3.28V / 0.2A
TLV62080EVM-756
It's probably a good idea to add an extra 22uF output cap to minimize the ripple in PFM at such low Vouts.
Where was the output voltage measured? Where is the TLV431 located, relative to the TLV62080 EVM? Can you share a photo of your setup?
You can measure the loop with a bode plot to assess stability with your components.
The TLV62080 uses a different power save mode, which has lower ripple and no intentional Vout change in PFM.
Hi Bogey,
many thanks for your inquiry. We do have a next generation for TLV62065 and TLV62080, which are respectively TLV62569 and TLV62568.
Below I have reported the comparison page (link and picture) where the main parameters are reported, including…
Yes, there could be a problem. This IC is older and not designed to work with large output filters.
TLV62080 or TLV62568 are newer and can support larger output caps.
