Analyzing the PCB layout.

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

Part information review

Project properties vs datasheet

Field	In project	Datasheet / official source	Status
Manufacturer Part Number	RAA2361052GNP#HC5	RAA2361052GNP#HC5	Match
Manufacturer Name	Renesas	Renesas Electronics	Acceptable
Part Type	Integrated Circuits	Ultra-low IQ buck-boost regulator with bypass	Acceptable but generic
Designator Prefix	IC	Not a datasheet mismatch, but nonstandard vs common `U` usage	Not critical
Package or Case Code	TO	10 Ld DFN, 0.5 mm pitch, L10.2.5x2.5	Mismatch
Datasheet URL	Present	Official Renesas page/datasheet available	Match

Key specs

Parameter	Value
Function	Ultra-low IQ buck-boost regulator with bypass
Input voltage	1.8 V to 5.5 V
Output voltage	1.8 V to 5.0 V
Output current	Up to 400 mA
Input quiescent current	130 nA
Peak efficiency	96%
Operating temperature	-40°C to +85°C
Package	10 Ld DFN, 0.5 mm pitch, L10.2.5x2.5
Exposed pad	Yes; must be soldered to GND

Symbol cross-check

Datasheet pinout says:

Table

Pin	Name	Function	Project status
1	EN	Enable input	Match
2	RSVD	Reserved, pull to GND	Match
3	BYPASS	Forced bypass control	Match
4	ILIM	Input current limit reader	Match
5	VSET	Output voltage reader	Match
6	VOUT	Output	Match
7	LX2	Boost switch node	Match
8	GND	Ground	Match
9	LX1	Buck switch node	Match
10	VIN	Input supply	Match
EPAD	EPAD	Exposed pad, connect to GND	Match

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

Item	Issue	Severity
Package or Case Code	`TO` in project vs 10 Ld DFN, L10.2.5x2.5 in datasheet	High
Pin Type properties	All pins are `Unspecified`	Medium
Pin descriptions	Missing	Medium
EPAD handling	Present and correctly broken out	OK
Pin names/numbers	Match datasheet	OK
Datasheet URL	Already set	OK

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

Fix package and pins

Set proper DFN package

Flag any footprint issues
