A steady 5.0 V, whatever the battery is doing

IMPR-POW-R-01 is a compact, breadboard-compatible synchronous buck-boost regulator module built around the TPS630702. Designed to sit after IMPR-POW-C-02, it converts the protected system rail into a regulated 5.0 V output for embedded prototypes, ESP32-class boards, radio adapters, and M1 bring-up work.

Designed and manufactured by Imperium Softworks. Schematic, layout, sourcing, assembly, and bring-up are handled in-house.

Compact buck-boost regulation for breadboard and M1 prototype power stages.
  1. 01 Protected system power (3.0–5.5 V) arrives on SYS_IN, typically from IMPR-POW-C-02.
  2. 02 The TPS630702 bucks or boosts automatically, whether the input is below, near or above 5 V.
  3. 03 A regulated 5.0 V rail leaves on VREG_OUT for ESP32 boards, radios and test loads.
  4. 04 Vertical 2.54 mm headers drop it straight onto a breadboard or into the RAD stack.
