Product description: D42V55F5.3 - step-down converter - 5.3 V 6 A - Pololu 5572
The Pololu D42V55F5.3 is a switching step-down converter that efficiently reduces input voltage to a stable 5.3V . Unlike linear regulators, it offers significantly higher energy efficiency , which translates into lower heat loss and longer battery life. The module supports a wide input voltage range from 5.3V to 60V and provides up to 6A of current, allowing it to power both digital systems and more demanding devices. Built-in safeguards, such as overheating, overload, and reverse polarity protection , ensure safe and stable operation.
Our offer also includes a version with an output voltage of 5 V - check it out!

Botland is an official distributor of Pololu electronics and robotics parts. Countless robots hold at least one component of this brand in their build. Our team guarantees that all Pololu products presented here are original.
The converter provides a stable voltage of 5.3 V.
Main features of the step-down converter
- Input voltage range : from 5.3 V to 60 V - wide range of applications
- Output voltage : 5.3 V (constant) - stable power supply
- Output current : up to 6 A - high current efficiency
- Efficiency : from 70% to 95% - energy-saving operation
- Operating frequency : approx. 400 kHz - stable operation
- Quiescent current : less than 0.2 mA - low power consumption
- Protection : thermal, overcurrent, reverse polarity
- Soft-start function : controlled voltage start-up
Pololu D42V55F5.3 step-down converter pinout
The module features a standard 2.54 mm pitch for easy use with breadboards and PCBs . The basic pins are VIN (power input), VOUT (voltage output), and GND (ground) , which are duplicated to improve current conduction. Additional pins expand the functionality of the system. EN allows for switching the converter on and off, which is particularly useful in energy-saving systems. PG (Power Good) indicates the correct output voltage, while the VRP pin provides access to the input voltage after protection.

DC-DC converter efficiency and current 5.3 V 6 A
The converter offers high efficiency ranging from 70% to 95% , significantly reducing energy loss and heat generation. Maximum efficiency is achieved with optimal load and moderate input voltage. The maximum continuous output current is up to 6 A , but its actual value depends on operating conditions such as input voltage, ambient temperature, and cooling method. At higher input voltages, available current may be reduced due to thermal constraints.
