TPS61043DRBT

Texas Instruments · LED Drivers · VSON-8-EP(3x3)

TPS61043DRBT from Texas Instruments, in a VSON-8-EP(3x3). 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	LED	input	Input of the internal LED switch (Q2) to which the LEDs connect, with V(LED) limited to 30 V maximum.
2	RS	output	Output of the internal LED switch where the sense resistor that programs LED current connects, with FB regulating the voltage across RS to 252 mV typical.
3	VIN	power_in	Input supply pin, operating from 1.8 V to 6 V with an absolute maximum of 7 V.
4	FB	input	Feedback pin that regulates the voltage across the sense resistor RS to 252 mV.
5	CTRL	input	Combined enable and PWM control pin: CTRL high (1.3 V minimum) enables the device, CTRL low (0.3 V maximum) disables it, and PWM signals of 100 Hz to 50 kHz set brightness.
6	GND	power_in	Ground pin, which is also connected to the exposed thermal die pad.
7	OVP	input	Overvoltage protection pin connected to the converter output capacitor, with V(OVP) limited to 30 V maximum.
8	SW	input	Drain of the integrated power switch (Q1), with a maximum switch voltage of 30 V.
9	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

Symbol: TPS61043DRBT
Footprint: Package_SON:VSON-8-1EP_3x3mm_P0.65mm_EP1.6x2.4mm
3D model: VSON-8-EP(3x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN 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: tps61043drbt-etched.step / tps61043drbt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps61043drbt.step / tps61043drbt.glb are the bare package body.
