Power Pal

Power Pal is a high-power, 3.3, 5 and 12 V DC-DC Step-Down Voltage Regulator that converts 14.5–52 V input (5-12s) into 3.3, 5 and 12 V rails simultaneously from a single module.

It is designed to power complete systems, motors, logic, and peripherals from one high-voltage source without juggling multiple converters, wiring harnesses, or protection circuits.

With 160 W continuous output and up to 250 W possible with active cooling, Power Pal features built-in protection, soft-start, external enable, and power-good monitoring, providing a clean, reliable power backbone that scales from bench prototypes to production hardware.

If you’re looking for something capable of providing 3.3, 5, 9 or 12 V at lower currents, check out the NanoBuck!

Description

Triple-Output High-Power Regulation

Simultaneously provides:

  • 12 V @ 10 A continuous (up to 16–20 A with active cooling). Up to 95% efficiency.

  • 5 V @ 5 A continuous (up to 6–7 A peak). Up to 88% efficiency.

  • 3.3 V @ 5 A continuous (up to 6–7 A peak). Up to 85% efficiency.

All rails are available at the same time and regulated independently, with adjustable output voltage trim to compensate for cable voltage drop.

Wide Input Range (14.5–52 V)

Suitable for 5S–12S lithium battery packs.

Integrated undervoltage lockout prevents brownout operation and unstable startup.

Comprehensive Protection Built In

  • Reverse polarity input protection (ideal-diode MOSFET)

  • Input TVS surge protection

  • TVS protection on all outputs

  • Overcurrent limiting on each rail

  • Overtemperature shutdown with hysteresis

  • Undervoltage lockout and fault handling

Designed to survive real-world wiring mistakes, load faults, and transient events.

Important Usage Notes

  • High-power regulators can reach dangerous temperatures under high load or high input-to-output voltage ratios. Do not touch during operation.
  • Always power down before connecting or disconnecting loads.
  • Long input or output wiring should use twisted pairs and local bulk capacitance.
  • Inductive loads (motors, solenoids, relays) generate voltage spikes when switched off, and motors can back feed energy into the regulator whenever they’re spun by momentum or external forces. Use flyback diodes and/or local TVS protection for spike suppression, and consider ideal diodes to block back feeding.
