My Texas Instruments LM5170EVM-BIDIR board refuses to deliver any output voltage when I switch it to buck mode. Boost mode also does not run, so I’m convinced the fault is somewhere in power stage or its sensing network. I haven’t probed or ruled anything out yet—no continuity checks, no component swaps—so you’ll be starting with a completely untouched setup. I do have both a multimeter and an oscilloscope on the bench, so I can feed you real-time measurements, screenshots, or scope traces as we move through your diagnostic plan. A hardware-level approach is exactly what I’m after: schematic review, expected waveforms, component-level tests, and, if it comes to it, guidance on swapping parts or jumpers to bring the regulator to life. Description: Controller: LM5170 EVM Mode: Buck (48V → 14.5V) Issue: Buck LED ON No output / incorrect output Bias supply confirmed (10V at J17) Fault pin behavior checked Suspected: Controller in shutdown / MOSFET issue Need: Hardware-level debugging support TI datasheet understanding Possibly schematic-level troubleshooting By the end of the engagement I expect: • A clear root-cause explanation for the “no output voltage” symptom in buck mode • A repeatable fix (circuit tweak, BOM change, or layout note) that I can implement and verify on my own bench • Confirmation through measured results that the buck rail is regulating correctly under load If you’ve debugged the LM5170—or similar multi-phase buck/boost controllers—your insight will save me days. Let’s get this board working.
