TD1468 from Techcode Semicon, in a ESOP-8. 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 | BST | passive | Bootstrap. Connect a capacitor between SW and BST pins to form a floating supply across the power switch driver. This capacitor drives the internal N-channel power MOSFET gate above the supply voltage. Absolute max: VSW - 0.3V to VSW + 6V. |
| 2 | VIN | power_in | Supply voltage input. Operates from a 10V-to-60V unregulated input (recommended 11V-60V). Requires an input bypass capacitor (e.g. 1μF ceramic plus bulk) to prevent large voltage spikes. Absolute max 60V. |
| 3 | EN | input | Enable / on-off control. Pull EN above 1.35V (typ) to turn the device ON; falling threshold 1.17V, ~180mV hysteresis. For automatic enable, connect to VIN through a 1MΩ resistor. Absolute max 6V. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to ground per PCB layout preference. |
| 5 | FB | input | Feedback input. Sets output voltage via an external resistor divider from VOUT to GND; internal reference is 0.812V (typ, 0.792-0.832V). A frequency foldback comparator lowers the oscillator frequency to ~120kHz when FB is below 300mV to prevent current-limit runaway during short-circuit faults. |
| 6 | NC | unconnected | No internal connection. Leave floating or tie to ground per PCB layout preference. |
| 7 | GND | power_in | Ground / voltage reference for the regulated output. Requires careful layout - isolate from the freewheeling diode (D1) to input-cap (C1) ground path to prevent switching current spikes from inducing noise into the reference. |
| 8 | SW | output | Power switching output. Drain of the internal N-channel power MOSFET (RDS(on) ~0.7Ω); connects to the external inductor and Schottky freewheeling diode of the LC output filter. Current limit ~2.8A typ. Absolute max -0.3V to VIN+0.3V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 367 faces against 152 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.
