SymbolFootprint3D modelPinsfor all variants

✓Datasheet: the page already carries TI's current edition (SNVSCS7E, April 2025, revised September 2026; sha256 9ecee6f360918744 matches ti.com/lit/ds/symlink/tpsm33620-q1.pdf fetched 2026-10-27); edition now recorded
✓Orderable TPSM33620S5QRDNRQ1 is the TPSM33620-Q1 2 A, 5V fixed / adjustable, spread-spectrum option (Device Comparison Table, p.4); Active, QFN-FCMOD RDN, 3000 large T&R, marking 33620S5Q (p.41)
✓All 11 pins match the Pin Functions table and Figure 5-1 (RDN 11-pin QFN-FCMOD top view, all variants, p.5) by number and name: PGOOD, EN, VIN, VOUT, SW, SW, BOOT, VCC, FB, GND, MODE/SYNC; no renames needed
✓Pin types against the table (A = analog, P = power, G = ground): PGOOD output -> open_collector (open-drain output), VCC output -> power_out (internal LDO output), BOOT input -> passive (internal bootstrap node, needs no external connection); SW 5/6 kept passive (switch node, must not be connected); VIN power_in, VOUT power_out, GND power_in, EN/FB/MODE/SYNC input
✓All 11 descriptions rewritten to the table wording (p.5); the earlier pin 5 and 6 text both said 'in parallel with pin 6', and others added facts not in the pin table (3V to 36V range on VIN, Auto/pulse-skipping wording)
✓Footprint vs RDN0011B (p.46-47, drawing 4231197/C 05/2026): 11 pads in TI's top-view arrangement, pin 1 top-left, 1-3 down the left, 4/5 large pads lower left/right, 6-8 up the right, 9/10/11 along the top. Copper vs TI's land pattern example: pins 2/3/6/7 1.20 x 0.35 at x = ±1.40, y = -1.15/-0.65 (TI 1.1 x 0.25 at y 1.15/0.65); pins 1/8 1.20 x 0.475 at y = -1.962 (TI 1.125 x 0.37 at y 1.96); pins 9/11 0.35 x 0.90 at x = ±0.50, y = -2.05 (TI 0.25 x 0.8 at x 0.5, y 2.06); pads 4/5 1.60 x 2.15 at (±1.20, 1.00) (TI land x 0.45-1.95, y 0.025-2.02); every copper pad covers TI's land
•Pads 4, 5 and 10 are copper-only with separate F.Mask/F.Paste polygons: pads 4/5 mask x ±0.45..±1.95, y -0.025..2.025 with the notched outer edge of TI's drawing; pin 10 mask/paste 0.30 x 1.525 at y -2.45..-0.924 (TI (0.3) x (1.52)); pin 10 copper continues 0.44 mm wide under the body between pads 4 and 5 to y = 2.075, under solder mask, like TI's ground strip with optional vias; copper-to-copper gap to pads 4/5 is 0.18 mm
✓3D model rebuilt (tier 3): the previous model, extracted from a board STEP (designer library Regulator_CDT), carried no licence. Tier 1 unusable: TI's RDN CAD is offered only through Ultra Librarian (reCAPTCHA + registration; its terms forbid creating libraries for distribution; the listed model is PSM33620S3QRDNRQ1). Tier 2: KiCad has no RDN0011B/QFN-FCMOD model. Hand-built in CadQuery from the RDN0011B outline (p.46, 4231197/C 05/2026), CC-BY-SA-4.0
✓3D body vs RDN0011B (p.46-47): 3.50 x 4.50 x 2.00 mm (D 3.4-3.6, E 4.4-4.6, A 1.9-2.1); pads 4/5 1.10 x 2.05 with four 0.25 x 0.2 tabs each at 0.30 + 0.5k; pins 2/3/6/7 0.25 x 0.90 at 0.65/1.15; pins 1/8 0.37 x 0.925 centred 1.96 (land pattern (1.96)), pin 1 chamfered; pins 9/11 0.25 x 0.60 at x = +/-0.5; pin 10 0.30 x 1.35; terminals 0.20 thick, exposed on the side walls as the side view shows. Overlaid on TI's bottom view at 157.6 px/mm, every edge on TI's lines (docs/proof/tpsm33620s5qrdnrq1-3d-vs-drawing.png)
✓Pose: Z-up, seated on z = 0, pin 1 top-left over pad 1 with a dimple in the drawing's pin-1 index area, footprint binding identity; step_pose.py PASS (centre 0.212 mm from the pad-pattern centre, which is asymmetric); MPN etched on top with adom-chip-laser 0.2.0; GLBs from step2glb 0.13.2 with PBR materials
•Not modelled: the outline's second line 0.05 mm inside the body edge (reference only) and the undimensioned tie-bar ticks on the bottom edge; A modelled at 2.00 (TI's outline view draws the 2.1 maximum)
✓DigiKey 296-TPSM33620S5QRDNRQ1TR-ND (tape and reel) and Mouser 595-SM33620S5QRDNRQ1 (both product URLs name TPSM33620S5QRDNRQ1) kept and added to specs
•The footprint still carries a hidden SUB property naming TPSM33610S5QRDNRQ1 (the 1 A option in the same RDN package and pinout, p.4-5) and the tag TPSM33625RDNR from the designer's library; these are not errors in the pads but are not this MPN
✓Symbol Datasheet / MPN / Manufacturer / DigiKey / Mouser / LCSC properties agree with page.json; footprint Datasheet property points at the manufacturer datasheet URL
✓component-page-verify: all checks pass; adom-lbr validate OK

reviewfor all variants

•3D model provenance: extracted from the source board STEP export (designer custom library Regulator_CDT); the upstream model licence is not stated, so the page licence is NOASSERTION.

reviewfor all variants

•The board stores this symbol under the library name Connector_Generic:Conn_02x03_Odd_Even (hand-edited) with cached fields naming TPSM33610S5QRDNRQ1 / TPSM33606S5QRDNRQ1; those fields are corrected on this page.
