TPS54340DDA from Texas Instruments, in a SOP-8-EP. 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 | BOOT | passive | Bootstrap capacitor is required between BOOT and SW; if the capacitor voltage falls below the minimum needed to operate the high-side MOSFET, the output is switched off until the capacitor is refreshed (abs max 53 V, BOOT-SW 8 V). |
| 2 | VIN | power_in | Input supply voltage with 4.5 V to 42 V operating range (absolute maximum 45 V). |
| 3 | EN | input | Enable terminal with internal pull-up current source; pull below 1.2 V to disable, float to enable, or use two resistors to adjust input undervoltage lockout (abs max 8.4 V). |
| 4 | RT/CLK | input | Resistor timing and external clock input: a resistor to ground sets the switching frequency, or pulling above the PLL upper threshold makes it a high-impedance synchronization clock input (abs max 3.6 V). |
| 5 | FB | input | Inverting input of the transconductance (gm) error amplifier (abs max 3 V). |
| 6 | COMP | output | Error amplifier output and input to the output switch current (PWM) comparator; connect frequency compensation components to this terminal (abs max 3 V). |
| 7 | GND | power_in | Ground terminal. |
| 8 | SW | passive | Source of the internal high-side power MOSFET and switching node of the converter (abs max 45 V, -0.6 V min). |
| 9 | PowerPAD | power_in | Thermal pad (GND) must be electrically connected to the exposed pad on the printed circuit board for proper operation. |
