TPS60133PWPR

Texas Instruments · DC-DC Converters · HTSSOP-20-EP

TPS60133PWPR 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 GND power_in Analog ground for the internal reference and control circuitry, to be connected to the PGND pins through a short trace.
2 GND power_in Analog ground for the internal reference and control circuitry, to be connected to the PGND pins through a short trace.
3 ENABLE input Enable input that must be connected to IN for normal operation; a logic low turns the device off, reduces supply current to 0.05 µA, and disconnects the output from the input.
4 FB input Feedback input to be connected to OUT as close to the load as possible, using an on-chip resistive divider that matches the internal 1.21-V reference.
5 OUT power_out Regulated 5-V power output to be connected together with OUT pin 16 through a short trace and bypassed to GND with the output filter capacitor CO.
6 C1+ passive Positive pin of the flying capacitor C1 of the charge pump.
7 IN power_in Supply input, bypassed to PGND with a capacitor of half the output capacitance and connected together with IN pin 14 through a short trace; operating input range is 2.7 V to 5.4 V.
8 C1- passive Negative pin of the flying capacitor C1 of the charge pump.
9 PGND power_in Power ground carrying the charge-pump current; all PGND pins must be connected together.
10 PGND power_in Power ground carrying the charge-pump current; all PGND pins must be connected together.
11 PGND power_in Power ground carrying the charge-pump current; all PGND pins must be connected together.
12 PGND power_in Power ground carrying the charge-pump current; all PGND pins must be connected together.
13 C2- passive Negative pin of the flying capacitor C2 of the charge pump.
14 IN power_in Supply input, bypassed to PGND with a capacitor of half the output capacitance and connected together with IN pin 7 through a short trace; operating input range is 2.7 V to 5.4 V.
15 C2+ passive Positive pin of the flying capacitor C2 of the charge pump.
16 OUT power_out Regulated 5-V power output to be connected together with OUT pin 5 through a short trace and bypassed to GND with the output filter capacitor CO.
17 LBO/PG output On the TPS60133 this is the Power Good open-drain output, which can sink 1 mA and should use a 100-kΩ to 1-MΩ pullup to OUT, or be left unconnected if unused.
18 LBI/NC unconnected On the TPS60133 this pin is not connected; the low-battery detector input function applies only to the TPS60130 and TPS60132.
19 GND power_in Analog ground for the internal reference and control circuitry, to be connected to the PGND pins through a short trace.
20 GND power_in Analog ground for the internal reference and control circuitry, to be connected to the PGND pins through a short trace.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TPS60133PWPR
  • 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: tps60133pwpr-etched.step / tps60133pwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps60133pwpr.step / tps60133pwpr.glb are the bare package body.
