Part Audit Mismatch


Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll audit the part metadata, locate and attach the official datasheet if needed, then cross-check the symbol, footprint, and pin descriptions against the manufacturer documentation.
The part already has an MPS datasheet URL. I’m verifying that source now and comparing the complete 24-pin map and QFN geometry against the stored symbol and footprint.

Part Audit Scope
Audit of MP4247GQV-0000 metadata, schematic symbol, PCB footprint, and terminal descriptions against the official Monolithic Power Systems MP4247 datasheet (MPS document viewer, document ID 9935; package information on pp. 39–40).
Stored Part Information Key Datasheet Specifications
  • Four-switch, single-inductor buck-boost converter with two integrated low-side MOSFETs and gate drivers for two external high-side N-channel MOSFETs.
  • Start-up input range: 3.6 V to 36 V; supports operation down to 2.8 V falling VIN when VOUT is above 3.5 V.
  • Output range: 1 V to 24 V, 1% accuracy for this variant family.
  • Rated capability: up to 5 A, 100 W, and up to 98% peak efficiency, subject to operating conditions and external component d...
Audit complete. The official MPS datasheet URL was already present, so no property update was needed; however, the part has a critical mismatch: the datasheet specifies a 20-pin QFN, while the symbol and footprint contain 24 pins/pads. The Logic / AND classification and missing pin types/descriptions are also incorrect.
Full specifications, pin map, and remediation details are in Part Audit. I also filed an internal part-quality report; this part should not be used or published until corrected.
