TX4152 from XDS, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW1 | output | Switch node 1. Internal high-side/low-side MOSFET drain output. Connect to the external inductor. Pins 1 and 2 (SW1/SW2) are tied together on the package. Absolute-max voltage -1V to 65V. |
| 2 | SW2 | output | Switch node 2. Connected internally with SW1; both pins should be tied together and connected to the inductor to reduce trace impedance. Absolute-max voltage -1V to 65V. |
| 3 | OUT | input | Output voltage sense pin. Connect to the converter's output rail for internal feedback/protection. |
| 4 | ISK | power_out | Internal LDO output. Decouple with a small ceramic capacitor to GND. Output range approximately 5V-11V (VISK). |
| 5 | EN | input | Enable input. Pull below ~0.3V to shut the chip down (IQ ≈ 300µA); drive above ~4.25V to enable. Recommended drive 4-5V. Absolute-max 65V. |
| 6 | FB | input | Feedback input for the internal error amplifier. Connect to an R5/R6 divider from OUT. VREF = 1.2V; VOUT = VREF·[1 + (R5/R6)]. |
| 7 | ILIM | input | Current-limit programming pin. Connect resistor RLIM to GND: RLIM(kΩ) = 34.2·IMAX(A) (datasheet also cites 32.5·Imax in application section). Absolute-max 6V. |
| 8 | FREQ | input | Switching-frequency programming pin. Connect resistor R1 from FREQ to GND: R1(kΩ) = 20900 / fosc(kHz). Leaving FREQ floating gives ~80 kHz; R1=120kΩ gives ~175 kHz. Absolute-max 6V. |
| 9 | GND | power_in | Ground return. Pins 9, 13, and 14 are all GND and should be tied to the system ground plane. |
| 10 | BOOST | passive | Bootstrap capacitor pin for the high-side MOSFET gate drive. Connect a small capacitor (e.g. 0.1µF) between BOOST and SW. Absolute-max 72V; BOOST-SW absolute-max 12V. |
| 11 | VIN1 | power_in | Power input, 8V to 60V. Tie pins 11 (VIN1) and 12 (VIN2) together and bypass with input capacitors close to the pin. Absolute-max 65V. |
| 12 | VIN2 | power_in | Power input, connected internally to VIN1. Tie to VIN1 (pin 11) at the package. |
| 13 | GND | power_in | Ground return. Tie to system ground plane together with pins 9 and 14. |
| 14 | GND | power_in | Ground return. Tie to system ground plane together with pins 9 and 13. |
