**Texas Instruments** · DC-DC Power Modules · DIP-10

PTH04T260WAD from Texas Instruments, in a DIP-10. 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 | SmartSync | input | Synchronizes the module switching frequency to an external clock with a SYNC high-level input of 2 V to 5.5 V; connect to GND (pin 3) if unused. |
| 2 | VI | power_in | Positive input voltage power node referenced to GND, operating over 2.2 V to 5.5 V. |
| 3 | GND | power_in | Common ground for the VI and VO power connections and the 0 Vdc reference for the control inputs. |
| 4 | VO | power_out | Regulated positive output, adjustable from 0.69 V to 3.6 V with respect to GND. |
| 5 | +Sense | input | Positive remote sense input that must be connected to VO close to the load for optimal voltage accuracy, and is also the reference terminal for the TurboTrans resistor. |
| 6 | -Sense | input | Negative remote sense input that must be connected to GND (pin 3) very close to the module (within 10 cm) for optimal voltage accuracy. |
| 7 | VO Adjust | passive | Output-voltage set pin where a 1%, 0.05 W, 100 ppm/°C (or better) resistor must be connected directly between this pin and -Sense (pin 6) to set the output above 0.69 V; if left open the output defaults to its lowest value. |
| 8 | TurboTrans | input | Transient-response adjust pin where a 1%, 0.05 W resistor connected to +Sense (pin 5) activates TurboTrans, and it must be left open-circuit if unused. |
| 9 | Track | input | Analog input that lets the output follow an external voltage volt-for-volt from 0 V up to the set-point voltage; connect to VI if unused. |
| 10 | Inhibit/UVLO | input | Negative-logic open-collector/drain inhibit where a low level referenced to GND disables the output, and a resistor to GND (pin 3) raises the UVLO ON threshold; leaving it open-circuit gives normal operation. |
