Part Information Review and Updates
Thought for 1 min 45 sec
I reviewed the current part definition for LM5190RGY, found that no Datasheet property is currently visible in the project metadata, and the official TI datasheet is:
I can update the part's Datasheet property to that official URL.
Current part metadata review
Table
| Field | In project now | Datasheet / official source | Status |
|---|---|---|---|
| MPN | LM5190RGY | TI ordering info shows LM5190RGYR in RGY package | Flag |
| Package | Not visible in current project metadata | 19-pin VQFN (RGY), 3.5 mm x 4.5 mm, exposed pad | Missing |
| Description | Project description is just LM5190RGY | 80 V synchronous buck controller with constant-current and constant-voltage regulation | Missing / too minimal |
| Datasheet URL | Not visible/set | Official TI PDF found | Missing |
| Pin count | 20 electrical items in project: 19 named pins + EP | 19 pins + exposed pad | Match |
Table
| Spec | Value |
|---|---|
| Device type | Synchronous buck controller, CC-CV |
| Input voltage range | 5 V to 80 V |
| Output voltage | 0.8 V to 79 V, or fixed 5 V / 12 V options |
| Switching frequency | 100 kHz to 2.2 MHz |
| Voltage regulation accuracy | ±1% |
| Current regulation accuracy | ±3% |
| Junction temperature | -40 C to 150 C |
| Package | RGY, 19-pin VQFN, 3.5 mm x 4.5 mm |
Table
| Project pin | Datasheet pin name | Result |
|---|---|---|
| ISET | ISET | Match |
| RT | RT | Match |
| COMP | COMP | Match |
| FB | FB | Match |
| AGND | AGND | Match |
| IMON_ILIM | IMON/ILIM | Minor naming mismatch |
| VCC | VCC | Match |
| PGND | PGND | Match |
| LO | LO | Match |
| VIN | VIN | Match |
| HO | HO | Match |
| SW | SW | Match |
| CBOOT | CBOOT | Match |
| BIAS | BIAS | Match |
| PG | PGOOD | Naming mismatch |
| FPWM_SYNC | FPWM/SYNC | Minor naming mismatch |
| EN | EN | Match |
| ISNS+ | ISNS+ | Match |
| VOUT | VOUT | Match |
| EP | EP | Match |
Table
| Check | Result |
|---|---|
| Footprint exists | Yes |
| Pad count | 20 pads present, including EP |
| Pin naming vs symbol | Consistent overall |
| Datasheet package style | Consistent with 19-pin VQFN + exposed pad |
| Geometry verification | Not fully provable from current layout metadata alone |
Table
| Item | Issue |
|---|---|
| Datasheet property | Missing |
| MPN normalization | Project uses LM5190RGY while TI ordering info shows LM5190RGYR |
| Package field | Missing from visible metadata |
| Description field | Too minimal |
| Pin descriptions | Not populated in the current symbol metadata |
| Pin types | All terminals are set to Unspecified, but datasheet defines Power / Ground / Input / Output types |
| Pin naming | PG vs PGOOD, FPWM_SYNC vs FPWM/SYNC, IMON_ILIM vs IMON/ILIM |
- The symbol pin count and footprint pad count look correct for this device.
- The main issues are metadata quality, not gross pinout failure.
- The most important flags are:
- missing Datasheet property
- likely incomplete MPN formatting
- missing package/description fields
- missing pin descriptions and pin types
- one real pin-name mismatch: PG should be PGOOD
If you want, I can update the Datasheet property to the official TI URL now.
