TLV62585: PSM mode VFB variation and feedforward capacitor value

Hi Kai,

Unfortunately, the device FB accuracy data is not available as a device transit to PWM mode in light load. Is there any application concern that requires these values? 

The feedforward capacitor for the TLV62585 device is optional to use. If you want to add the capacitor to improve the performance, I would suggest following the app note that can help to optimize the value: https://www.ti.com/lit/an/slva289b/slva289b.pdf

Hi Tanvee,

TLV62585 works as PSM mode in customer target current range and they need to know output voltage accuracy so I asked FB accuracy data at PSM mode.

I will share feedforward capacitor link, thanks!

Hi Kai,

It is difficult to define the data in PSM mode as it depends on many factors like the output caps and operating conditions. I would be recommended sharing a schematic, layout, and external components if customer concerns about the voltage regulation.

Hi Tanvee,

If I share schematic, external components and (layout this should be optional), you can do corner analysis of VFB?
