TPS53313RGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 pin for device on/off control. |
| 2 | PG | output | Power good output flag; open drain output requiring pull-up resistor to external rail. |
| 3 | VIN | power_in | Gate driver supply and power conversion voltage input; 4.5 V to 16 V. |
| 4 | VIN | power_in | Gate driver supply and power conversion voltage input; 4.5 V to 16 V. |
| 5 | VIN | power_in | Gate driver supply and power conversion voltage input; 4.5 V to 16 V. |
| 6 | VIN | power_in | Gate driver supply and power conversion voltage input; 4.5 V to 16 V. |
| 7 | PGND | power_in | Device power ground terminal. |
| 8 | PGND | power_in | Device power ground terminal. |
| 9 | PGND | power_in | Device power ground terminal. |
| 10 | PGND | power_in | Device power ground terminal. |
| 11 | PGND | power_in | Device power ground terminal. |
| 12 | PGND | power_in | Device power ground terminal. |
| 13 | SW | output | Output inductor connection to integrated power devices; switching node. |
| 14 | SW | output | Output inductor connection to integrated power devices; switching node. |
| 15 | SW | output | Output inductor connection to integrated power devices; switching node. |
| 16 | SW | output | Output inductor connection to integrated power devices; switching node. |
| 17 | VBST | power_in | Supply input for high-side MOSFET (bootstrap terminal); connect capacitor from this pin to SW terminal. |
| 18 | BP7 | power_in | Bias supply for internal circuitry and driver. |
| 19 | BP3 | power_in | Input bias supply for analog functions. |
| 20 | AGND | power_in | Device analog ground terminal. |
| 21 | RT/SYNC | bidirectional | Synchronized to external clock; program switching frequency 250 kHz to 1.5 MHz by connecting resistor to GND or connect to external clock source. |
| 22 | MODE/SS | input | Mode configuration pin; connect resistor to GND for mode selection and soft-start time (1 ms, 3 ms, or 6 ms); capacitor selection changes current limit threshold to 4.5 A, 6 A, or 9 A. |
| 23 | COMP | output | Error amplifier compensation terminal; Type III compensation method recommended for stability. |
| 24 | FB | input | Voltage feedback pin for OVP, UVP, and power good determination; voltage range 0 to 3.5 V. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
