Hi team,
can you look into the following inquiry please?
With TPS61089 we have built up a boost converter (5 V to 12 V @ 500 mA). Unfortunately, the output voltage of the controller clearly shows the switching pulses, which are also visible in the EMC measurements.
The actual ripple is ok with approx. 20 mV.
In the screenshots you will find the circuit diagram and the layout as well as the measurements at the output of the controller (C117/12V). The controller was loaded with 24 Ohm (500 mA) during the measurements.
Maybe you have some information for us how we can solve the problem with the peaks.
Thank you for your efforts in advance.
Best regards,
Franz
