# TPS5420D reference design ## Description This TPS5420D reference design is a step-down voltage regulator providing a stable 5V output from a higher input voltage. It uses capacitors, an inductor, and a diode for filtering and protection, with an EN terminal for control. Ideal for applications needing a regulated 5V supply. #referenceDesign #project #stepDown #voltageRegulator #5V #TPS5420 #powermanagement #texas-instruments #template #reference-design #polygon ## Project Details - **Owner:** vasy_skral - **Created:** 5/15/2023 - **Last Updated:** 3/5/2026 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **Copies:** 5 ## Key Components ### D1 — [PDS760-13](https://www.flux.ai/vasy_skral/pds760-13~tul.md) - Part Type: Diode - Manufacturer Name: Diodes Incorporated - License: https://creativecommons.org/licenses/by/4.0/ - Datasheet URL: https://www.diodes.com/assets/Datasheets/ds30477.pdf - Manufacturer Part Number: PDS760-13 **Pins:** - A1 [pin 2] - A2 [pin 3] - K [pin 1] ### IC1 — [TPS5420D](https://www.flux.ai/vasyl/tps5420d~xs2.md) - Part Type: Integrated Circuit - Datasheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Ftps5420 - Manufacturer Part Number: TPS5420D - Manufacturer Name: Texas Instruments **Pins:** - BOOT [pin 1] - ENA [pin 5] - GND [pin 6] - NC [pin 3] - NC [pin 2] - PH [pin 8] - VIN [pin 7] - VSNS [pin 4] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/vasy_skral/tps5420d-reference-design~yp](https://www.flux.ai/vasy_skral/tps5420d-reference-design~yp).* --- *Generated from [https://www.flux.ai/vasy_skral/tps5420d-reference-design~yp](https://www.flux.ai/vasy_skral/tps5420d-reference-design~yp)*
