# TPS61202DSCR

**Texas Instruments** · Global Sourcing Parts · WSON-10-EP(3x3)

TPS61202DSCR from Texas Instruments, in a WSON-10-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 | VAUX | bidirectional | Supply voltage for the control stage, specified as an I/O pin in the datasheet. |
| 2 | VOUT | power_out | Boost converter output; the 5 V fixed-output version delivers up to 600 mA at 5 V with VIN of 3 V or higher. |
| 3 | L | passive | Connection for the boost inductor. |
| 4 | PGND | power_in | Power ground, which must be connected to the exposed thermal pad. |
| 5 | VIN | power_in | Boost converter input voltage, rated 0.3 V to 5.5 V. |
| 6 | EN | input | Enable input (High = enabled, Low = disabled); do not leave floating. |
| 7 | UVLO | input | Undervoltage lockout comparator input; must be connected to VAUX if not used. |
| 8 | PS | input | Enables or disables Power Save mode (High = disabled, Low = enabled); do not leave floating. |
| 9 | GND | power_in | Control and logic ground. |
| 10 | FB | input | Voltage feedback for adjustable versions; must be connected to VOUT for fixed-output versions such as the 5 V TPS61202. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
