Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VPWR | power_in | Chip supply / VBUS input source from the front-stage AC-DC or DC-DC output. Recommended 10 µF decoupling to GND; operating range 3.6-21 V (UVLO rising 3.3 V, falling 2.9 V). |+| 2 | VPWR | power_in | Chip supply input, internally tied to pin 1. Both pins carry the front-stage supply current into the die. |+| 3 | OPTO | output | Opto-coupler drive output that closes the primary-side feedback loop of the AC-DC front stage, letting the chip adjust the VBUS rail dynamically for PD/PPS. |+| 4 | VFB | input | System voltage regulation feedback pin, tied to the system voltage feedback divider (recommended R_FB1 = 100 kΩ, R_FB2 = 33 kΩ). |+| 5 | IREF | passive | CC loop compensation node; connect a compensation network (typ. R = 10 kΩ, C = 10 nF) to GND. Leave floating if the constant-current function is not used. |+| 6 | GND | power_in | Device ground reference for analog, digital and power sections. |+| 7 | CSN | input | Current-sense negative input across the external 10 mΩ shunt R_S1. Tie to GND if the constant-current function is not used; must not be left floating. |+| 8 | CSP | input | Current-sense positive input across the external 10 mΩ shunt R_S1. Tie to GND if the constant-current function is not used; must not be left floating. |+| 9 | LINK | bidirectional | XPD-LINK™ shared bus terminal for inter-chip communication in multi-port chargers; pull the shared bus to GND via a 10 kΩ resistor. May be left floating if not used. |+| 10 | DIS | output | Gate-drive output for the external discharge NMOS (bleeder). R_ON of internal N1 is 40 Ω typ (100 Ω max). |+| 11 | AISN | input | Cascade current-sense negative input, used only when cascading with a non-XPD-series part. Connect to GND when not used. |+| 12 | AISP | input | Cascade current-sense positive input, used only when cascading with a non-XPD-series part. Connect to GND when not used. |+| 13 | NC | unconnected | No internal connection; leave floating. |+| 14 | NC | unconnected | No internal connection; leave floating. |+| 15 | CC1 | bidirectional | USB Type-C configuration channel 1: performs DFP Rp advertisement (3 A / 1.5 A) and BMC PD communication. 24 V abs-max, OVP protected. |+| 16 | DP | bidirectional | USB Type-C D+ data line, used for BC1.2, Apple 2.4 A, QC and HVDCP handshakes. 24 V abs-max, OVP protected. |+| 17 | DM | bidirectional | USB Type-C D− data line, used for BC1.2, Apple 2.4 A, QC/FCP/SCP/AFC handshakes. 24 V abs-max, OVP protected. |+| 18 | CC2 | bidirectional | USB Type-C configuration channel 2: performs DFP Rp advertisement (3 A / 1.5 A) and BMC PD communication. 24 V abs-max, OVP protected. |+| 19 | VBUS | power_out | USB Type-C VBUS output from the integrated 10 mΩ high-side switch; supports up to 20 V/3.25 A (65 W). Requires a 2.2-10 µF cap to GND; pins 19 and 20 must be tied together. |+| 20 | VBUS | power_out | USB Type-C VBUS output, internally tied to pin 19; carries the output current of the internal switch MOSFET. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen Fuman |+| Package | TSSOP-20 |+| Category | PMIC |+| Pins | 20 |++## Ordering variants++Same part, different packaging or reel option.++- `XPD930A`+- `XPD930B`+- `XPD930D30A`+- `XPD930D30`+- `XPD930DP30`+- `XPD930D45`+- `XPD930DP45`+- `XPD930D60`+- `XPD930DP60`+- `XPD930D65`+- `XPD930DP65`+- `XPD930D6545`+- `XPD930QXXXXX`++## CAD (KiCad official)++- Symbol: `XPD930B`+- Footprint: `Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm`+- 3D model: TSSOP-20 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shenzhen Fuman datasheet](docs/xpd930b-datasheet.pdf) (19 pp, sha256 `48a8084240110c9d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
