TPS92511DDAR

Texas Instruments · LED Drivers · SO-8-EP

TPS92511DDAR from Texas Instruments, in a SO-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_out Internal regulator output, typically regulated to 5.4 V. Connect a capacitor larger than 1 µF between VCC and GND.
2 PGND power_in Power Ground. Must be connected to the GND pin for normal operation. The PGND and GND pins are not internally shorted.
3 IADJ input Average LED current setting. An external resistor R_IADJ connecting IADJ to ground programs the average LED current. IADJ pin voltage is typically 1.25 V.
4 GND power_in Analog Signal Ground.
5 FS input Switching frequency setting. An external resistor R_FS connecting FS to ground programs the switching frequency from 50 kHz to 500 kHz (e.g. 500 kHz typical at R_FS = 20 kΩ).
6 DIM input PWM Dimming Control. Apply a logic-level PWM signal to dim the LED string. Internally pulled up. Upper threshold typ 1.0 V, lower threshold typ 0.44 V.
7 LX output Integrated MOSFET drain. Internally connected to the drain of the integrated low-side N-channel MOSFET. Connect to the output inductor and anode of the Schottky diode. R_DS(on) typ 1.4 Ω.
8 VIN power_in Input voltage supply pin to the device. Input voltage range 4.5 V to 65 V (67 V transient).
9 Thermal Pad power_in Thermal connection pad. Connect to a ground plane for heat dissipation.

  • TPS92511DDAR

CAD (KiCad official)

  • Symbol: TPS92511DDAR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SO-8-EP (KiCad packages3D, STEP)
  • 3D model files: tps92511ddar-etched.step / tps92511ddar-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps92511ddar.step / tps92511ddar.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps92511ddar.step 123 KB You want the bare part, or you mark your own boards.
tps92511ddar-etched.step 2.3 MB You want the part with TPS92511DDAR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 581 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
