Description: The DSN6009 is a high-performance step-up (BOOST) module with 4A switching current. The module uses the second generation of high frequency switching technology XL6009E1 as the core chip, performance far beyond the first generation of technology LM2577. XL6009 step-up module cost lower, more outstanding performance, LM2577 module is about to be eliminated. ultra-wide input voltage 3V ~ 32V, the best working voltage range is 5 ~ 32V; ultra-wide output voltage of 5V ~ 35V; built-in 4A high efficiency MOSFET switch, the efficiency of up to 94%; (LM2577 current only 3A) ultra-high switching frequency of 400KHz, you can use a small capacity of the filter capacitor that can achieve very good results, smaller ripple, smaller. (LM2577 frequency only 50KHz) Note: This clockwise buck, counterclockwise boost
