# TPS40210QDGQRQ1

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

TPS40210QDGQRQ1 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 | RC | input | Switching-frequency setting input; external capacitor and resistor to VDD program converter frequency (maximum 10V). |
| 2 | SS | input | Soft-start time programming input; external capacitor to GND programs soft-start time and overcurrent timeout (maximum 10V). |
| 3 | DIS/EN | input | Disable/enable input with internal 1-MΩ pulldown to GND; pulling high enters shutdown mode (maximum 10V). |
| 4 | COMP | output | Error amplifier output connected through compensation network to FB pin (maximum 9V). |
| 5 | FB | input | Error amplifier inverting input; voltage divider from output determines output voltage via compensation network to COMP (maximum 10V). |
| 6 | GND | power_in | Device ground. |
| 7 | ISNS | input | Current sense input; external resistor to GND provides feedback for overcurrent detection at 150mV typical threshold (maximum 8V). |
| 8 | GDRV | output | Gate driver output; connects to N-channel MOSFET gate (maximum 9V). |
| 9 | BP | output | Regulator output; 1-μF bypass capacitor connects from this pin to GND (maximum 9V). |
| 10 | VDD | power_in | System input voltage; operating range 4.5V to 52V with bypass capacitor to GND (maximum 52V). |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
