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
