Product description: D42V55F5 - step-down converter - 5 V 6 A - Pololu 5571
The Pololu D42V55F5 converter is a switching buck ( step-down ) voltage regulator that efficiently reduces input voltage to a stable 5V . Unlike linear regulators, it offers significantly higher energy efficiency , which translates into lower heat loss and longer battery life. The system supports a wide input voltage range from 5V to 60V and features protection against overheating, overload, and reverse polarity. The maximum continuous current is 6A .
Our offer also includes a version with an output voltage of 5.3 V - check it out!

Pololu D42V55F5 step-down converter pinout
The module features a standard 2.54 mm pitch for easy integration with breadboards and PCBs . Basic pins include VIN (power input), VOUT (output), and GND (ground) , which are duplicated for increased current efficiency. Additional functional pins are available: EN ( for power on/off) and PG (Power Good) , which indicates the correct output voltage. The VRP pin provides access to the input voltage after reverse polarity protection. This solution allows for easy monitoring of the system's operation and integration with more advanced control and power systems.

Efficiency and current of the DC-DC converter 5 V 6 A
The converter offers high efficiency ranging from 80% to 95% , minimizing energy loss and heat generation. This is particularly important in mobile projects and battery systems. The maximum continuous output current is typically up to 6 A , but this value depends on the input voltage and cooling conditions. At higher input voltages, the available current may decrease due to thermal constraints. Thanks to the use of switching technology, the regulator ensures stable voltage even under variable load, ensuring reliable operation of the powered devices.
