TPS40009DGQR

Texas Instruments · DC-DC Converters · HVSSOP-10

TPS40009DGQR from Texas Instruments, in a HVSSOP-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 ILIM input Current-sink input (15 µA) for overcurrent threshold; external resistor sets voltage between (VDD−0.8) V and VDD.
2 FB input Feedback input to error amplifier; regulated voltage is 700 mV internal reference.
3 COMP output Error amplifier output for PWM duty-cycle modulation.
4 SS/SD input Soft-start and shutdown input with 3-µA charge current; shutdown occurs when voltage falls below 0.25 V.
5 GND power_in Power supply return and PowerPAD heat slug connection point.
6 LDRV output Low-side MOSFET gate driver output with 10-35 ns rise/fall times.
7 VDD power_in Power supply input, 2.25-5.5 V range; decouple with ≥1-µF low-ESR capacitor.
8 SW output Switched node connection for overcurrent and predictive gate-drive delay sensing; high-side driver return path.
9 HDRV output High-side MOSFET gate driver output bootstrapped to approximately 2 × VDD with 10-35 ns rise/fall times.
10 BOOT output Bootstrap supply output (VSW + 6.5 V maximum) for high-side gate driver charging.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS40009DGQR
  • Footprint: Package_SO:HVSSOP-10-1EP_3x3mm_P0.5mm_EP1.83x1.89mm
  • 3D model: HVSSOP-10, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal HVSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tps40009dgqr-etched.step / tps40009dgqr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps40009dgqr.step / tps40009dgqr.glb are the bare package body.
