Texas Instruments · LED Drivers · HTSSOP-20-EP

TPS61199PWPR 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 FBP output LED short-across protection threshold program pin; set using external resistor divider to program overvoltage threshold.
2 COMP output Loop compensation output pin; connect RC network to optimize feedback loop stability and transient response.
3 FSW output Boost switching frequency selection pin; connect resistor to program frequency 300-800 kHz using Fs = 80,000/R(kΩ).
4 ISET output Full-scale LED current selection pin; connect resistor to program LED current up to 70 mA per string using 1.229 V reference.
5 EN input Enable/disable control pin; high ≥2 V enables device, low ≤0.8 V disables device.
6 PWM input PWM dimming signal input pin; accepts 100 Hz to 22 kHz frequency for brightness control with up to 5000:1 dimming ratio at 200 Hz.
7 IFB1 input Regulated current sink input for LED string 1; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
8 IFB2 input Regulated current sink input for LED string 2; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
9 IFB3 input Regulated current sink input for LED string 3; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
10 IFB4 input Regulated current sink input for LED string 4; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
11 IFB5 input Regulated current sink input for LED string 5; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
12 IFB6 input Regulated current sink input for LED string 6; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
13 IFB7 input Regulated current sink input for LED string 7; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
14 IFB8 input Regulated current sink input for LED string 8; sinks up to 70 mA with ±2% accuracy and 3% inter-string matching.
15 GND power_in Ground pin; system ground connection including PowerPAD thermal pad in HTSSOP package.
16 ISNS input External MOSFET current sense positive input pin; monitors inductor current with 120-180 mV overcurrent protection threshold.
17 GDRV output External switch MOSFET gate driver output pin; 2 Ω source impedance and 1.5 Ω sink impedance at 6 V.
18 VIN power_in Supply input pin; accepts 8-30 V input voltage for boost converter and can be tied to voltage different from power stage input.
19 VDD power_out Internal regulator output pin; 5.7-6.3 V output requiring 2.2 µF bypass capacitor to ground, 15 mA maximum sourcing current.
20 OVP input Overvoltage protection threshold pin; program output clamp voltage using external resistor divider.
21 PowerPAD passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS61199PWPR
  • 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: tps61199pwpr-etched.step / tps61199pwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps61199pwpr.step / tps61199pwpr.glb are the bare package body.
