The VDS (drain-to-source) voltage is also as expected, and the CDD capacitor charges up to around 21 V and then discharges.

However, as you are not seeing voltage across any test points, please do cross check with multimer across complete board if something got damaged. Also, apply low Vin and check trace it from input to output, up to what point your getting expected voltage. As said no Vdd, please check all component in Vdd circuit why its coming open circuit. Thanks Regards Anitahttps://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1648396/ucc28710-uc28710-startup-issue/6355872Fri, 22 May 2026 09:34:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:6137defe-e792-416b-bce6-0216483c4cb7Kalyani RautHello Anita, The board is not powering up, and no switching or signal is observed at any test point, indicating that the controller is not initiating startup.

Specifically, I am looking for: Transient simulation models Importable simulation projects/files .obj, .lib, .tsc, or any associated schematic/project files compatible with PSpice/TINA-TI/SIMetrix For TPS16630PWPR, I could only find partial model files where all pins are not exposed properly for simulation. I would appreciate it if you could share the complete schematic/project or any available reference transient models. For LM5069MM-1/NOPB as well, I would like to know if any transient simulation project or importable model is available. The intention is to directly import the project and use it for transient analysis and protection testing simulations.

I think the controller is just hitting a fault protection like UVLO, OVP, or OCP, but I can't figure out which specific one it is or what's causing it.

As for your 1.5A application, TPS61236 is a high current boost, so we still suggest that you could use TLV61070A， TPS61099， TPS61299.
