TPS5430QDDARQ1

Texas Instruments · DC-DC Converters · SOP-8-EP

TPS5430QDDARQ1 from Texas Instruments, in a SOP-8-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 BOOT output Boost capacitor for the high-side FET gate driver; connect a 0.01µF low ESR capacitor rated for at least 10V from BOOT to PH.
2 NC unconnected No connect, not internally connected.
3 NC unconnected No connect, not internally connected.
4 VSENSE input Feedback voltage for the regulator; connect to the output voltage divider.
5 ENA input On and off control: below 0.5V the device stops switching and above 1.3V it starts switching; it has an internal 1.5MΩ pullup, so do not connect it to ground through a resistor.
6 GND power_in Ground; connect to DAP, which must be connected to the exposed pad for proper operation.
7 VIN power_in Input supply voltage; bypass to GND with a high quality low ESR ceramic capacitor placed within 1mm of the VIN pin and within 1mm of the GND pin.
8 PH output Source of the high side power MOSFET, connected to the external inductor and diode.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
