Forum Post: RE: UCC28810EVM-003 Start up delay
The EVM as I said was optimized with this delay for general use to mitigate stress on power components. While it may be reduced this may impact reliability on startup. This is a high power LED driver...

Hi John,The D/S has graphs for 1.2Vout, so this is close enough for you to get the idea. If you want higher, you'll need to use a higher current part like TPS62080.

Does anyone know if this product is still supported? It appears that no one uses it.
View ArticleForum Post: RE: Is this really the Iq for the TPS62260?
Usually the lower Iq current specs are with the device in PFM mode not switching. The spec you referred to is with the device in PWM mode, switching.I just escalated the DDR4 post with the BU.

Hi All,My customer is looking for an IC that protects his equipment if the battery voltage goes over 1.5V. The battery holder can take 1.5V batteries and 2V batteries they want the protection IC to...
View ArticleForum Post: RE: Disabling the Voltage Feed-Forward in TPS40057
Hi Soo,I think the long turn-on delay may be caused by the overcurrent protection, not because of the input UVLO. Can you send your schematic? There are several things I would like to check, like RLIM...
