Description:
Synchronous rectification technology introduction:
1. Synchronous rectification is a new technology that uses a dedicated power MOSFET with extremely low on-resistance to replace the rectifier diode to reduce the rectification loss.
2. It can greatly improve the efficiency of the DC/DC converter and there is no dead zone voltage caused by the Schottky barrier voltage.
3. The power MOSFET is a voltage-controlled device, and its volt-ampere characteristic is linear when it is turned on.
4. When using a power MOSFET as a rectifier, the gate voltage must be synchronized with the phase of the rectified voltage to complete the rectification function, so it is called synchronous rectification. 5. Synchronous rectification technology greatly reduces the rectification loss at the output end of the switching power supply, thereby improving the conversion efficiency and reducing the heat of the power supply itself.
Module parameters:
1. Rectification mode: synchronous rectification
2. Type: Non-isolated buck module (BUCK)
3. Input voltage: 8-55V (limit 60V, please leave margin)
4. Output voltage: 1-35V continuously adjustable. Please be careful not to exceed this range when adjusting the voltage.
5. The input voltage of the buck power supply should always be greater than the output voltage and there should be at least a 1V voltage difference. Input power = output power + loss (energy conservation principle)
6. Output current: 15A (MAX) The current marked within 10A for a long time is the maximum current under specific conditions (measured 12V drop 5V) The actual output current is not fixed and is related to the input and output voltage difference, temperature, and other conditions
7. Output power: With good ventilation and natural heat dissipation, the long-term power is 100W, and the maximum power with enhanced heat dissipation can reach 200W. If working for a long time, please leave a margin, pay attention to the temperature rise, and do a good job of heat dissipation.
8. Working temperature: -10~+85 degrees
9. Working frequency: 180KHz
10. Conversion efficiency: up to 94% (efficiency is related to input and output voltage difference and output current)
11. Short circuit protection: Yes (short circuit output current is 0)
12. Reverse polarity protection: Yes
13. Wiring method: high current terminal block, no welding required, IN+: positive input, IN-: negative input, OUT+: positive output, OUT-: negative output
14. Aluminum shell size: 70MM*38MM*31MM
15. Weight: Approx. 80g
