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 Dimensions 43mm * 21mm * 14mm (L * W * H) 3) LM2596 cu display voltmetru: 20ron Rectification mode:Non-synchronous rectifier Input voltage:3V-40V Output voltage:1.3V-35V Output current:Rated current is 2A,maximum 3A(Additional heatsink is required) Conversion efficiency:92%( highest ) Switching frequency:65KHz Output ripple:30mV( maximum ) Load regulation: 0.5% Voltage regulation: 2.5% Work temperature:-Minus 40 degrees - 85 degrees dimension:43mm*21mm*14mm(L*W*G) NOTE:This can't be used to step up Voltage
