The module uses the second generation of high-frequency switching technology XL6009E1 core chip performance than the first generation technology LM2577. XL6009 boost module at a lower cost, superior performance, LM2577 module is about to be eliminated. ● Wide input voltage 3V ~ 32V, optimum operating voltage range is 5 ~ 32V; ● Wide Output voltage 5V ~ 35V; ● Built-4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A) ● high switching frequency 400KHz, can use a small-capacity filter capacitors that can achieve very good results, the ripple smaller and smaller. (LM2577 frequency only 50KHz) Technical parameters: Model Specification:DSN6009 boost module Module Properties:Non-isolated boost (BOOST) Rectification:Non-Synchronous Rectification Input Range:3V ~ 32V Output Range:5V ~ 35V Input Current:4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current.) Conversion efficiency:<94% (greater the pressure, the lower the efficiency) Switching frequency:400KHz Output Ripple:50mV (the higher the voltage, the greater the current, the greater the ripple) Load Regulation:± 0.5% Voltage Regulation:± 0.5% Operating Temperature:-40 ℃ ~ +85 ℃ Size:43x21x14mm   Package: 1 x XL6009 DC-DC Adjustable Step-up Power Converter Module
