TPS61193PWPR

Texas Instruments · LED Drivers · HTSSOP-20-EP

TPS61193PWPR from Texas Instruments, in a HTSSOP-20-EP. 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 VIN power_in Input power supply pin (4.5 to 40 V).
2 LDO power_out Output of internal low-dropout regulator; connect 1-μF decoupling capacitor to noise-free ground.
3 FSET input DC-DC switching frequency setting; connect external resistor from 24 kΩ to 219 kΩ between this pin and ground.
4 VDDIO/EN power_in Enable input and supply voltage (VDDIO) for digital logic circuits.
5 FAULT tri_state Open-drain fault signal output; leave floating if unused.
6 SYNC input Boost synchronization input; connect to GND to disable or VDDIO/EN to enable spread spectrum.
7 PWM input PWM brightness control input signal.
8 NC unconnected No-connect pin.
9 GND power_in Ground connection.
10 ISET input LED current setting; connect external resistor from 24 kΩ to 129 kΩ between this pin and ground.
11 GND power_in Ground connection.
12 GND power_in Ground connection.
13 OUT3 output Current sink output for LED string 3; connect to GND if unused.
14 OUT2 output Current sink output for LED string 2; connect to GND if unused.
15 OUT1 output Current sink output for LED string 1; connect to GND if unused.
16 FB input Boost/SEPIC feedback input; connect to resistor divider midpoint between output and ground (5 to 150 kΩ resistors).
17 PGND power_in DC-DC power ground connection.
18 SW output DC-DC converter switching output for boost or SEPIC topology.
19 NC unconnected No-connect pin.
20 VIN power_in Input power supply pin (4.5 to 40 V).
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS61193PWPR
  • Footprint: Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm
  • 3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP 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: tps61193pwpr-etched.step / tps61193pwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps61193pwpr.step / tps61193pwpr.glb are the bare package body.
