Looking for "Official datasheet details for RAA2361052GNP#HC5: exact manufacturer part number, manufacturer, package name/package code, pin count, exposed pad presence, short functional description, input voltage range, output voltage range, maximum output current, quiescent current, efficiency, and operating temperature range." in raa236105-ultra-low-iq-buck-boost-regulator-bypass

Looking for "Complete pin table for RAA2361052GNP#HC5 with pin numbers, pin names, and short functions for all pins including EPAD if present." in raa236105-ultra-low-iq-buck-boost-regulator-bypass

Looking for "Package and footprint information for RAA2361052GNP#HC5: package type, number of leads/pads, whether there is an exposed pad, and any identifying dimensions or package drawing references." in raa236105-ultra-low-iq-buck-boost-regulator-bypass

I reviewed the part metadata, symbol terminals, and footprint against the official Renesas datasheet, using the datasheet as the source of truth as recommended for part-project verification
Summary
  • The Datasheet URL property is already set, so I did not search the web or change that property.
  • The part is broadly identified correctly as a Renesas buck-boost IC.
  • The main metadata mismatch is the package property:
    • Project: Package or Case Code = TO
    • Datasheet: 10 Ld DFN, 0.5 mm pitch, L10.2.5x2.5
  • The symbol terminal count matches the datasheet:
    • Datasheet: 10 leads + exposed pad
    • Project: 11 terminals total, including EPAD
  • The terminal names and pin numbers match the datasheet.
  • The biggest symbol-data gap is that all terminals are currently Pin Type: Unspecified and there are no pin descriptions. For a part-project audit, those should be populated from the datasheet rather than left blank

Symbol findings
  • Pin count matches exactly: 11 total items including EPAD, which is the correct way to treat the exposed pad for part verification
  • Pin names match
  • Pin numbers match
  • No extra terminals found
  • No missing terminals found
Symbol issues flagged
  • All terminals currently have Pin Type: Unspecified
  • I do not see Pin Description properties on the terminals
  • I also do not see richer symbol metadata like Section, Pin Group, or orientation assignments
For an IC-style part, those are incomplete relative to the recommended part-project setup
Footprint cross-check
From the layout:
  • There is a footprint with pads for all named pins plus EPAD
  • Pad names present:
    • EN, RSVD, BYPASS, ILIM, VSET, VOUT, LX2, GND, LX1, VIN, EPAD
Footprint findings
  • Pad count matches the datasheet package concept: 10 leads + exposed pad
  • Pad naming matches the pinout
  • EPAD is present, which is required by the datasheet
Footprint issue flagged
  • The project package metadata says TO, which does not match the actual DFN package/fingerprint identity from the datasheet.
    This is the clearest footprint/metadata mismatch.

Mismatches and gaps

ItemIssueSeverity

Pin Type propertiesAll pins are UnspecifiedMedium
Pin descriptionsMissingMedium
EPAD handlingPresent and correctly broken outOK
Pin names/numbersMatch datasheetOK
Datasheet URLAlready setOK
Bottom line
The part is mostly structurally correct:
  • correct MPN
  • correct manufacturer
  • correct terminal count
  • correct pin names
  • correct pin numbering
  • correct inclusion of EPAD
The two things I’d flag are:
  • Package metadata is wrong/incomplete (TO should be replaced with the actual DFN package code)
  • Terminal metadata is incomplete because pin types and descriptions have not been populated from the datasheet
If you want, I can fix the part project next by:
  • updating Package or Case Code
  • assigning Pin Type for all 11 terminals
  • adding short Pin Description text for each pin
