DC-DC Adjustable Step Down Module 15A

Introduction To Synchronous Rectification Technology:

Synchronous rectification is a new technology that uses dedicated power MOSFETs with extremely low on state resistance to replace rectifier diodes and reduce rectification losses. It can greatly improve the efficiency of DC/DC converters and there is no dead time voltage caused by Schottky barrier voltage. Power MOSFETs belong to voltage controlled devices, and their volt ampere characteristics exhibit a linear relationship during conduction. When using power MOSFETs as rectifiers, it is required that the gate voltage must be synchronized with the phase of the rectified voltage in order to complete the rectification function, hence it is called synchronous rectification. Synchronous rectification technology greatly reduces the rectification loss at the output end of the switching power supply, thereby improving conversion efficiency and reducing the heating of the power supply itself.

Module Parameters:

● Rectification method: synchronous rectification

● Type: Non isolated buck module (BUCK)

● Input voltage: 8-55V (limit 60V, please leave margin)

● Output voltage: When adjusting the voltage continuously from 1-35V, please be careful not to exceed this range. The input voltage of the step-down power supply should always be greater than the output voltage and there should be at least 1V voltage difference in Z. Input power=output power+loss (energy conservation principle)

● Output current: 15A (MAX) for a long time. The marked current within 10A is the Z large current under specific conditions (measured 12 drops by 5V). The actual output current size is not fixed and is related to conditions such as input and output voltage difference, temperature, etc

● Output power: With good ventilation, the natural heat dissipation power is 100W for a long time, and the enhanced heat dissipation can reach up to 200W. If working for a long time, please leave a margin to pay attention to temperature rise and heat dissipation.

● Operating temperature: -10~+85 degrees Celsius

● Operating frequency: 180KHz

● Conversion efficiency: 94% higher in Z (efficiency is related to input, output voltage difference, and output current)

● Short circuit protection: Yes (short circuit output current is 0)

● Reverse protection: Yes

● Wiring method: high current terminal, soldering free, IN+: input positive, IN -: input negative, OUT+: output positive, OUT -: output negative

● Aluminum shell size: 70MM * 38MM * 31MM

● Weight: approximately 80g
