Input voltage: DC10-90V Output voltage: DC1.5-60V (suitable for applications where the input voltage is higher than the output voltage and the voltage cannot be boosted). Output current: MAX6A (please derate when using high-voltage output, and heat dissipation is required when the temperature exceeds 65 degrees). Maximum power: 100W (the maximum current at low voltage output is 6A. Maximum power at high voltage output is 100W) Operating frequency: 180KHz<br><br>Conversion efficiency: 97.5% (typical) Working temperature: -40℃ to +85℃ Adjustment direction of potentiometer: clockwise (increase) and counterclockwise (decrease) Connection mode: terminal board Synchronous rectifier is a technology, which uses special power MOSFETs with extremely low on-resistance to replace rectifier diodes to reduce rectifier losses. It can greatly improve the efficiency of DC/DC converter and has no dead-time voltage caused by Schottky barrier voltage. Power MOSFET is a voltage-controlled device, and its volt-ampere characteristics are linear when it is turned on. When power MOSFET is used as 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. Synchronous rectification technology greatly reduces the rectification loss at the output of switching power supply, thus improving the conversion efficiency and reducing the heat generated by the power supply itself.
