  RE: TPS62153: TPS62153 output to input protection

  It's still not perfectly clear what your setup is: do you have big caps on input or output or both? But it is ok to remove the input voltage from the device. There will always be some output voltage left and this is ok--it will be sunk by the load...

  RE: TPS62153 output resistive divider value?

  Welcome to the forums. I retitled your post to begin with the part number. The internal divider only pulls a few uA. A major point of using an internal one is that it can be made higher impedance compared to an external divider since it is more noise...

  TPS62153 latch-up / damage

  I am using the TPS62153 as a pre-regulator that steps +12V DC down to +5V DC as an input for a secondary buck regulator which makes dual 3.3V supplies. The design appears to work as expected, but after a day or so of nominal operation 62153 goes into...

  RE: TPS62130, the thermal control doesn't intervenes

  Hi, the output capacitor C31 is a 100 uF WCAP-PSLP 875105242010 aluminum polymer capacitor with ESR= 30 mOhm, while the input capacitor C29 is a ceramic. As you can see in the annexed TPS62133 PCB.pdf the two capacitors are very closed to the device...
