TPS54418RTER 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 with operating range from 2.95 V to 6 V. |
| 2 | VIN | power_in | Input supply voltage with operating range from 2.95 V to 6 V. |
| 3 | GND | power_in | Power ground, should be connected directly to the exposed power pad under the device. |
| 4 | GND | power_in | Power ground, should be connected directly to the exposed power pad under the device. |
| 5 | AGND | power_in | Analog ground, should be electrically connected to GND close to the device. |
| 6 | VSENSE | input | Inverting input of the transconductance error amplifier connected to resistor divider from output voltage. |
| 7 | COMP | output | Error amplifier output with frequency compensation components connected; internally compared to switch current. |
| 8 | RT/CLK | input | Resistor timing or external clock input: 85 kΩ to 1000 kΩ resistor sets switching frequency from 200 kHz to 2000 kHz, or external clock with minimum 75 ns pulse width. |
| 9 | SS | input | Soft-start pin where external capacitor sets output voltage rise time; charged by 1.8 μA internal current source. |
| 10 | PH | output | Switching node connecting the source of the high-side power MOSFET and drain of the low-side synchronous rectifier MOSFET. |
| 11 | PH | output | Switching node connecting the source of the high-side power MOSFET and drain of the low-side synchronous rectifier MOSFET. |
| 12 | PH | output | Switching node connecting the source of the high-side power MOSFET and drain of the low-side synchronous rectifier MOSFET. |
| 13 | BOOT | input | Bootstrap supply pin requiring 0.1 μF ceramic capacitor between BOOT and PH; monitored by UVLO with 2.1 V minimum threshold at 2.95 V input. |
| 14 | PWRGD | output | Open-drain power good output pulled low when VSENSE falls below 93% or rises above 107% of 0.8 V reference. |
| 15 | EN | input | Enable pin with internal pull-up current source; pull below 1.25 V threshold to disable; external resistors adjust UVLO. |
| 16 | VIN | power_in | Input supply voltage with operating range from 2.95 V to 6 V. |
| 17 | Thermal Pad | power_in | Exposed power pad soldered to PCB ground plane with multiple vias for thermal and mechanical performance. |
