Part Information Review and Updates
Thought for 1 min 24 sec
I reviewed the part project against the datasheet and the current part definition.
Part info review
Current project metadata
Table
| Field | Current value | Datasheet check | Status |
|---|---|---|---|
| Manufacturer Part Number | XL4016 | Matches datasheet MPN | OK |
| Manufacturer Name | XLSEMI | Matches datasheet manufacturer | OK |
| Description | 8A 180KHz 40V Buck DC to DC Converter | Matches datasheet description | OK |
| Datasheet URL | already set | Present, so no web lookup/update was needed | OK |
| Package or Case Code | TO | Datasheet package is TO220-5L | Mismatch |
| Designator Prefix | PS | Not contradicted by datasheet | OK |
Table
| Parameter | Value |
|---|---|
| Function | Buck DC-DC converter |
| Package | TO220-5L |
| Switching frequency | 180 kHz fixed |
| Recommended input range | 8 V to 36 V |
| Adjustable output range | 1.25 V to 32 V |
| Load capability | 8 A |
| Constant output current capability | 12 A |
| Max efficiency | up to 96% |
| Protection/features | thermal shutdown, current limit, short-circuit protection |
What matches
- The five numbered terminals in the schematic match the datasheet names and numbers exactly.
- The footprint also contains pads named GND, FB, SW, VC, and VIN, so the basic pad naming is aligned with the symbol.
Table
| Area | Issue | Severity |
|---|---|---|
| Package metadata | Project says TO, datasheet says TO220-5L | Medium |
| Pin count | Datasheet also lists the metal tab connected to SW, but the project currently has only 5 terminals | High |
| Pin types | All terminals are still set to Unspecified: GND, FB, SW, VC, VIN | High |
| Pin descriptions | No pin descriptions are populated on the terminals | High |
| Symbol completeness | No dedicated terminal for the exposed/tab connection, even though exposed pads/tabs should be represented when listed in the datasheet | High |
Footprint check
- I could confirm the footprint has pads for the five named pins.
- I could not fully verify pad geometry/mechanical dimensions from the currently returned layout data.
- The main footprint-level concern is still the same: the datasheet package is TO220-5L, while the project metadata is only TO, and the metal tab tied to SW is not represented as its own terminal.
For part-project verification, the datasheet should be treated as the source of truth, pin numbers must match exactly, and exposed/thermal pads count as pins when the datasheet lists them .
Summary
- Good: MPN, manufacturer, description, and the 5 numbered pin names/numbers are correct.
- Needs fixing: package metadata, pin types, pin descriptions, and likely the missing metal tab = SW terminal.
- No datasheet URL action needed: a datasheet URL is already set, so I did not search/update it.
If you want, I can fix the part metadata and terminal properties next.
