TPS51604DSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | BST | input | High-side N-channel FET bootstrap voltage input; power supply for high-side driver; voltage range -0.3 V to 35 V (transient to 38 V <20 ns). |
| 2 | PWM | input | PWM input with tri-state gate driver control; tri-state window 1.3-2.0 V disables both output drivers for low-power mode; voltage range -0.3 V to 6 V. |
| 3 | SKIP | input | Mode selection input with tri-state capability; low enables zero-crossing detection (DCM mode), high disables (FCCM mode), tri-state enables very-low-power mode; voltage range -0.3 V to 6 V. |
| 4 | VDD | power_in | 5-V power supply input for driver IC; recommended operating voltage 4.5-5.5 V; decouple to GND with ≥1 µF ceramic capacitor. |
| 5 | DRVL | output | Synchronous low-side N-channel gate drive output; drives low-side MOSFET gate with rise time 15 ns and fall time 10 ns into 3.3 nF load; voltage range -0.3 V to 6 V. |
| 6 | GND | power_in | Synchronous low-side N-channel gate drive return and device reference ground; tie thermal pad to system GND plane with multiple vias for thermal performance. |
| 7 | SW | bidirectional | High-side N-channel gate drive return and zero-crossing sense input; detects inductor current zero-crossing for DCM operation; voltage range -1 V to 28 V. |
| 8 | DRVH | output | High-side N-channel gate drive output; drives high-side MOSFET gate with rise time 30 ns and fall time 8 ns into 3.3 nF load; voltage range -0.3 V to 6 V (transient to 38 V). |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
