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 3V32V, optimum operating voltage range is 532V;Wide Output voltage 5V35V;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 SpecificationDSN6009 boost moduleModule PropertiesNon-isolated boost (BOOST)RectificationNon-Synchronous RectificationInput Range3V32VOutput Range5V35VInput Current4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA.
