Hi，

The design schematic diagram of LMZ13610 is shown below. Could you please help check if there are any issues? Or good advice？

    Hi Jeno,

    1. Output capacitors are missing. One recommended output capacitor combination is two 330-μF, 15-mΩ ESR tantalum polymer capacitors connected in parallel with a 47-uF 6.3-V X7R ceramic. This combination provides excellent performance that may exceed the requirements of your applications and you can decide based on your actual test results. Additionally some small 47-nF ceramic capacitors can be used for high-frequency EMI suppression. 

    2. Leave the place for a 50ohm resistor between VO and the upper feedback resistor R276 in case the loop test is needed.

    3. Leave the place for a feedforward capacitor across the upper feedback resistor R276 to help tune the loop.

    You can also take a look at the EVM user's guide for the reference.
