Texas Instruments · Power Management - Specialized · WQFN-20-EP(3x3)
TPS65235-3RUKR from Texas Instruments, in a WQFN-20-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 | LX | input | Switching node of the boost converter. |
| 2 | VIN | power_in | Input of the internal linear regulator (recommended VIN operating range is 4.5 V to 20 V). |
| 3 | VCC | power_in | Internal 6.3-V power supply that needs a 1-µF ceramic capacitor to ground, and is connected to VIN when VIN is 5 V. |
| 4 | AGND | power_in | Analog ground; all ground pins and the power pad must be connected together. |
| 5 | TCAP | output | A capacitor on this pin sets the rise time of the LNB output. |
| 6 | ISET | output | A resistor on this pin sets the LNB output current limit (external resistor set, ±10% accuracy per the description). |
| 7 | EN | input | Enables the VLNB output when high; pulling it to ground disables the output and allows I2C register access. |
| 8 | FAULT | output | Open-drain output that goes low when any fault flag is set. |
| 9 | ADDR | input | A resistor on this pin selects the I2C address (see the I2C Address Selection table 7-4). |
| 10 | VCTRL | input | Logic voltage level on this pin sets the LNB output voltage (see the logic table 7-3). |
| 11 | SDA | bidirectional | I2C-compatible bidirectional data line. |
| 12 | SCL | input | I2C-compatible clock input. |
| 13 | EXTM | input | External modulation logic input that activates the 22-kHz tone output; it accepts a 22-kHz tone or a logic high or low signal. |
| 14 | DOUT | output | Tone detection output. |
| 15 | DIN | input | Tone detection input. |
| 16 | VLNB | power_out | Output of the power supply connected to the satellite receiver or switch. |
| 17 | VCP | output | Gate-drive supply voltage and charge-pump output; a capacitor is connected between this pin and VLNB. |
| 18 | BOOST | power_out | Output of the boost regulator and input voltage of the internal linear regulator. |
| 19 | GDR | output | Controls the gate of the external MOSFET for DiSEqC 2.x support. |
| 20 | PGND | power_in | Power ground for the boost converter. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
