TPS54618RTER from Texas Instruments, in a WQFN-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 | VIN | power_in | Input supply voltage operating range is 2.95 V to 6 V. |
| 2 | VIN | power_in | Input supply voltage operating range is 2.95 V to 6 V. |
| 3 | GND | power_in | Power ground pin that must be electrically connected directly to the exposed power pad under the device. |
| 4 | GND | power_in | Power ground pin that must be electrically connected directly to the exposed power pad under the device. |
| 5 | AGND | power_in | Analog ground pin that should be electrically connected to GND close to the device. |
| 6 | VSENSE | input | Inverting input node of the transconductance error amplifier for feedback network connection. |
| 7 | COMP | output | Error amplifier output connected to output switch current comparator and frequency compensation network. |
| 8 | RT/CLK | bidirectional | Resistor timing input or external clock input pin for setting switching frequency from 300 kHz to 2000 kHz. |
| 9 | SS/TR | bidirectional | Slow-start and tracking pin where external capacitor sets output voltage rise time and can be used for supply sequencing. |
| 10 | PH | output | Output of the high-side power MOSFET source and low-side synchronous rectifier drain forming the switching node. |
| 11 | PH | output | Output of the high-side power MOSFET source and low-side synchronous rectifier drain forming the switching node. |
| 12 | PH | output | Output of the high-side power MOSFET source and low-side synchronous rectifier drain forming the switching node. |
| 13 | BOOT | input | Bootstrap capacitor connection (0.1 μF ceramic X5R or X7R dielectric recommended) for high-side gate drive biasing. |
| 14 | PWRGD | tri_state | Open-drain power good output signal that asserts low for thermal shutdown, overcurrent, or over/undervoltage fault conditions. |
| 15 | EN | input | Enable input pin with internal pull-up current source; pull below 1.2 V to disable or float to enable device operation. |
| 16 | VIN | power_in | Input supply voltage operating range is 2.95 V to 6 V. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
