Power Pal
One module turns a 14.5–52 V source into regulated 3.3 V, 5 V and 12 V rails, all at the same time.
Power Pal converts a 14.5–52 V input into simultaneous 12 V, 5 V and 3.3 V outputs. It supplies up to 160 W at 25 °C, or 250 W with active cooling, with independent regulation and built-in protection.
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.
For a direct battery connection, use a BMS or a low-voltage cutoff. The UVLO is not battery protection.
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
Integrated undervoltage lockout prevents brownout operation and unstable startup.
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.
