Part Review Mismatches

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 inspect the part metadata, find and attach the official datasheet if missing, then compare symbol/footprint/pin details against it and record a concise review.

flux

The part already has an official Mean Well datasheet URL set, so I’ll use that for verification rather than changing it.

The pin map and nominal footprint geometry match the datasheet; I’m writing the detailed spec/mismatch report now.

Reviewed the NLDD-700H part and created the detailed report: NLDD-700H Part Review.

The datasheet URL was already set, so I did not change it. Pinout and nominal footprint geometry match the Mean Well datasheet, but the library description has spec mismatches: input/output voltage, dimming type, efficiency, and operating temperature need correction; symbol pin descriptions/types are also missing.

NLDD-700H Part Review

Date: 2026-07-16

Scope

Reviewed available part information for the published Flux component NLDD-700H against the official Mean Well NLDD-H datasheet. Items checked: MPN, manufacturer, package/mechanical data, pin count, description/properties, schematic symbol terminals, footprint pads, and pin descriptions.

Datasheet

Existing Datasheet URL property was already set: https://www.meanwell-web.com/content/files/pdfs/productPdfs/MW/NLDD-H/NLDD-H-spec.pdf
No datasheet property update was required.
Datasheet family/file identified by extraction: Mean Well NLDD-H-SPEC, dated 2024-10-16.

Current Flux Part Information

Table

Field	Current value	Review
Manufacturer Part Number	NLDD-700H	Matches datasheet order number.
Manufacturer Name	Mean Well	Matches datasheet/manufacturer.
Designator Prefix	PS	Reasonable for PCB-mount power supply / LED driver module.
Mount	PCB	Acceptable, though `Through-hole PCB module` would be more descriptive if available.
Part Type	Optoelectronic Devices	Broad but acceptable; more specific category would be DC/DC constant-current LED driver or LED driver module.
Datasheet URL	Mean Well NLDD-H PDF	Present; no update needed.
Terminal count	9	Matches the 9 populated pins for the blank NLDD-350H to NLDD-1050H type.
Package/case	Module / PCB mount	Consistent with the datasheet module form factor.

Key Datasheet Specs for NLDD-700H

Output voltage	6 to 52 VDC
Output current	700 mA constant current
Current accuracy	+/-5% typical at 48 VDC input
Efficiency	Up to 96%
Ripple and noise	200 mVp-p max.
Switching frequency	200 kHz
Dimming/control	PWM dimming and remote ON/OFF
PWM frequency	100 Hz to 1 kHz
ON threshold	DIM to -VIN > 2.5 to 5 VDC, or open circuit
OFF threshold	DIM to -VIN 2.5 to 5 V to -VIN; OFF if <0.8 V or short to -VIN.

Footprint Cross-Check

Current footprint raw KiCad pad map:

Table

Pad	Function	Coordinate (mm)	Pad/drill
1	-VIN	(0, 0)	1.3 mm TH pad, 0.8 mm drill
2	-VIN	(0, -2.54)	1.3 mm TH pad, 0.8 mm drill
11	-VOUT	(0, -25.4)	1.3 mm TH pad, 0.8 mm drill
12	-VOUT	(0, -27.94)	1.3 mm TH pad, 0.8 mm drill
13	+VOUT	(-15.24, -27.94)	1.3 mm TH pad, 0.8 mm drill
14	+VOUT	(-15.24, -25.4)	1.3 mm TH pad, 0.8 mm drill
22	PWM DIM	(-15.24, -5.08)	1.3 mm TH pad, 0.8 mm drill
23	+VIN	(-15.24, -2.54)	1.3 mm TH pad, 0.8 mm drill
24	+VIN	(-15.24, 0)	1.3 mm TH pad, 0.8 mm drill

Footprint outline and spacing:

Body/fab outline: 20.5 x 32.1 mm, matching datasheet nominal body size.
Pin columns: 15.24 mm apart, matching datasheet.
Row pitch between populated adjacent pins: 2.54 mm, consistent with the datasheet drawing.
Courtyard clearance: about 1 mm beyond body outline, reasonable.
Pin 1 is rectangular; this is useful for orientation.

Footprint Findings

Pad count, pad numbers, and nominal XY geometry match the datasheet pin table and mechanical drawing for the NLDD-350H to NLDD-1050H blank type.
Drill is 0.8 mm for a 0.60 mm pin. This is likely usable, but assembly tolerance may be improved with 0.9 to 1.0 mm drill and an adjusted pad diameter if annular ring allows.
The datasheet mechanical figure is labeled bottom view. The current footprint appears plausible, but final approval should include a visual orientation check against the datasheet view convention to ensure it was not mirrored. Pin 22 location is the key asymmetry to verify.

Mismatches / Issues Flagged

Table

Severity	Area	Finding	Datasheet-backed correction
High	Library description	Description says 6 to 36 V input.	Should be 10 to 56 VDC input, 59 VDC max.
High	Library description	Description says output up to 32 VDC.	Should be 6 to 52 VDC output.
Medium	Library description	Description says 95% efficiency.	Datasheet states up to 96%.
Medium	Library description	Description says analog dimming.	Datasheet extraction supports PWM dimming / remote ON/OFF on pin 22; no analog dimming was found in the reviewed extraction.
Medium	Library description	Description says -40 to +70 degC operating range.	Datasheet working temperature is -40 to +50 degC, with derating curve; storage is -40 to +85 degC.
Medium	Symbol metadata	Pin descriptions are missing.	Add datasheet-backed descriptions, especially `-VIN` not connected to `-VOUT`.
Medium	Symbol metadata	All terminal `Pin Type` values are `Unspecified`.	Use appropriate Power In / Power Out / Input classifications.
Low	Footprint assembly margin	0.8 mm drill for 0.60 mm pins may be tight.	Consider 0.9 to 1.0 mm drill with corresponding pad diameter if manufacturing rules allow.
Low / verify	Footprint orientation	Nominal pad map matches, but datasheet view is bottom view.	Perform one visual orientation verification before final release.

Overall Verdict

The core pinout and nominal footprint geometry are consistent with the official Mean Well datasheet for the NLDD-700H blank-type module. The main issues are metadata/description accuracy and incomplete symbol pin metadata, not the pad numbering itself. The highest-priority corrections are the input/output voltage ranges, dimming wording, operating temperature wording, and explicit -VIN/-VOUT separation warning in pin descriptions.
