TPS62420DRCR from Texas Instruments, in a VSON-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ADJ2 | input | Adjust pin for converter 2 output voltage. Connect an external resistor divider between VOUT2 and GND to set the output between 0.6 V and VIN. If EasyScale interface is used for converter 2, this pin must be connected directly to the output. |
| 2 | MODE/DATA | bidirectional | Dual-function pin. Operation mode select: low = PFM/PWM auto power-save, high = forced PWM. Also acts as the EasyScale one-wire serial data interface (open-drain acknowledge, sink current <= 500 uA). Active when EN1 or EN2 is high. |
| 3 | VIN | power_in | Supply voltage input, connect to VBAT. Operating range 2.5 V to 6 V (abs max 7 V). |
| 4 | FB1 | input | Direct feedback voltage sense input for converter 1, connect directly to VOUT1. Internal feed-forward capacitor is connected between this pin and the error amplifier. For fixed output versions or when the EasyScale interface is used, this pin ties to an internal resistor divider network. |
| 5 | DEF_1 | bidirectional | Defines the output voltage of converter 1. On the TPS62420 (adjustable) it is an analog input for the external resistor divider that sets the default output voltage. On TPS62421 (fixed) it is a digital input selecting between two preset default outputs. |
| 6 | SW1 | passive | Switch node of converter 1. Connect to the external inductor (typ. 2.2 uH). Abs max -0.3 V to 7 V. |
| 7 | EN1 | input | Enable input for converter 1, active high. VIH >= 1.2 V, VIL <= 0.4 V. |
| 8 | GND | power_in | Ground reference for both converters. Should be connected to the PowerPAD. |
| 9 | EN2 | input | Enable input for converter 2, active high. VIH >= 1.2 V, VIL <= 0.4 V. |
| 10 | SW2 | passive | Switch node of converter 2. Connect to the external inductor (typ. 2.2 uH). Abs max -0.3 V to 7 V. |
| 11 | PowerPAD | power_in | Exposed thermal pad on the bottom of the package. Must be connected to GND for proper thermal and electrical performance. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 590 faces against 74 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
