DSN6009 4A is a high-performance step-up switching current (BOOST) module. 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)
