# TPS62040DGQR

**Texas Instruments** · DC-DC Converters · HVSSOP-10-EP-0.5mm

TPS62040DGQR from Texas Instruments, in a HVSSOP-10-EP-0.5mm. 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 | EN | input | Enable input; pulling EN to ground forces device into shutdown, pulling EN to VI enables device. |
| 2 | VIN | power_in | Supply voltage input, operating range 2.5 V to 6.0 V. |
| 3 | VIN | power_in | Supply voltage input, operating range 2.5 V to 6.0 V. |
| 4 | GND | power_in | Analog ground. |
| 5 | FB | input | Feedback pin; connect directly to output for fixed output voltage version, or through external resistor divider for adjustable version. |
| 6 | MODE | input | Mode control input; pulling high forces fixed frequency operation, pulling low enables power save mode with PWM at high load and PFM at light load. |
| 7 | SW | bidirectional | Switch pin connected to drain of internal power MOSFETs. |
| 8 | SW | bidirectional | Switch pin connected to drain of internal power MOSFETs. |
| 9 | PGND | power_in | Power ground; must be connected to PowerPAD. |
| 10 | PGND | power_in | Power ground; must be connected to PowerPAD. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
