  • Forum Post: Re: Do any one used TPS62060?

    Chris Glaser
    David, Yes, the TPS62060 works well when used correctly. I encourage you to read the datasheet and follow the recommendations for selecting the external components and the layout recommendations. These must be followed for proper operation. To evaluate our ICs, we highly recommend that you order...

  • Forum Post: Re: Low frequency harmonic waveform in tps62065 output

    Chris Glaser
    This occurs when the IC is operated in PFM mode. When it automatically transitions to PWM mode at higher loads, the device must still check for PFM mode in order to keep the efficiency high. It needs to know when to leave PWM mode so it must check. This checking circuit is what you are seeing on the...

    Chris Glaser
    Q: Can the TPS6206x safely start into an output that is pre-biased to some voltage? Will it sink current from the output? A: Yes, these devices start normally into a pre-bias. Here is an example of the EVM (configured to give 1.8V out) starting into a 1V pre-bias: (Please visit the site to...

  • Forum Post: RE: Problems Regarding to Switching Regulator Output

    Chris Glaser
    You will need to make sure your board was assembled correctly and with no solder shorts. These are the most common reasons for seeing 0V at the output. Your board layout does not follow any of the recommendations for a good power supply layout, so I expect you will have layout issues. I suggest ordering...

  • Forum Post: RE: Inquiry regarding EN pin on TPS62510

    Chris Glaser
    Per the D/S, the device is disabled when the EN pin is low. So, it is off. Both switching FETs are open. You might also look at the newer TPS62080, TPS62060, or TPS62090.
