Why Synchronous Rectification?
Synchronous rectification is an advanced switching power supply technology that replaces traditional rectifier diodes with ultra-low on-resistance power MOSFETs. This eliminates the Schottky barrier voltage drop and significantly reduces rectification losses — resulting in higher efficiency, less heat output, and a longer-lasting power supply module. The MOSFET gate voltage is precisely synchronized with the rectified voltage phase to ensure optimal performance at all times.

Frequently Asked Questions
Q: What is the input voltage range for this buck regulator module?
A: This DC buck converter module accepts an input voltage of DC 10V to 90V. It steps the voltage down to an adjustable output of DC 1.5V to 60V — the input voltage must always be higher than the desired output voltage for proper operation.
Q: Do I need a heat sink with this buck power supply module?
A: At standard loads and ambient temperatures, the module runs efficiently at up to 97.5% conversion efficiency. However, when operating above 65°C or at high-voltage/high-current output levels, it is recommended to derate the current and add active or passive heat dissipation to ensure long-term stable performance.
Q: How do I adjust the output voltage on this buck converter?
A: Output voltage is adjusted using the onboard potentiometer. Turn it clockwise to increase the output voltage and counter-clockwise to decrease it. The module uses a terminal board connection for easy wiring integration into your project.
