TPS53311RGTR from Texas Instruments, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable input. Internally pulled up to VDD with a 1.35-MΩ resistor. |
| 2 | SYNC | bidirectional | Synchronization signal for input interleaving. Master SYNC pin sends out 180° out-of-phase signal to slave SYNC. SYNC frequency must be within ±20% of slave nominal frequency. |
| 3 | PGD | output | Power good output flag, open drain output. Pull up to an external rail through a resistor. |
| 4 | VBST | power_in | Supply input for high-side MOSFET (bootstrap terminal). Connect capacitor from this pin to SW terminal. |
| 5 | SW | bidirectional | Output inductor connection to integrated power devices. |
| 6 | SW | bidirectional | Output inductor connection to integrated power devices. |
| 7 | SW | bidirectional | Output inductor connection to integrated power devices. |
| 8 | PS | input | Mode configuration pin (with 10 µA current): Connecting to ground for Forced CCM slave, pulled high or floating for Forced CCM master, or connect to GND with 24.3 kΩ for DE slave, 57.6 kΩ for HEF mode, 105 kΩ for reserved mode, or 174 kΩ for DE master. |
| 9 | COMP | output | Error amplifier compensation terminal. Type III compensation method is recommended for stability. |
| 10 | FB | input | Voltage feedback input. Also used for OVP, UVP, and PGD determination. |
| 11 | AGND | power_in | Device analog ground terminal. |
| 12 | VDD | power_in | Input bias supply for analog functions. Nominal 3.3-V input voltage range 2.9 V to 3.5 V. |
| 13 | VIN | power_in | Gate driver supply and power conversion voltage input. VIN supply voltage range 2.9 V to 6 V. |
| 14 | VIN | power_in | Gate driver supply and power conversion voltage input. VIN supply voltage range 2.9 V to 6 V. |
| 15 | PGND | power_in | IC power ground terminal. |
| 16 | PGND | power_in | IC power ground terminal. |
| 17 | PAD | power_in | Exposed thermal pad. Must be soldered to printed circuit board. Connect to power ground through multiple vias for thermal and mechanical performance. |
