Matek Power Module PM12S-3
by Matek Systems

The PM12S-3 Power Module is a versatile and high-performance DC-DC step-down (buck) regulator designed to handle wide input voltages ranging from 9V to 55V. Ideal for powering a range of high-performance electronics, this power module features 3 independent voltage regulators, offering output options of 5.2V, 6V, and 8V with up to 15A continuous current and 25A peak current for each. A dedicated 5V and 12V fixed output is also available, supporting up to 4A continuous current.

This synchronous switching regulator delivers exceptional efficiency (90% to 96%) and minimal output ripple, making it perfect for applications where stable power delivery is critical, such as drones, RC vehicles, and other high-power electronics. Additional protection features include overcurrent protection, thermal shutdown, short-circuit tolerance, and self-recovery, ensuring safe and reliable operation.
