Ultra-wide input voltage 3V~32V, the best working voltage range is 5~32V;Ultra-wide output voltage 5V~35V;Built-in 4A high-efficiency MOSFET switch, making the efficiency up to 94%; (LM2577 current is only 3A)The ultra-high switching frequency is 400KHz, which can achieve very good results with small-capacity filter capacitors, with smaller ripple and smaller volume. (LM2577 frequency is only 50KHz)technical parameter:Model Specifications: DSN6009 Boost ModuleModule nature: non-isolated boost (BOOST)Rectification method: Asynchronous rectificationInput range: 3V~32VOutput range: 5V~35VInput current: 4A (maximum), no-load 18mA (5V input, 8V output, no-load less than 18mA. The higher the voltage, the greater the no-load current.)Conversion efficiency: <94% (the greater the pressure difference, the lower the efficiency)Switching frequency: 400KHzOutput ripple: 50mV (the higher the voltage, the greater the current, the greater the ripple)Load Regulation: ±0.5%Voltage regulation: ±0.5%Working temperature: -40℃~ +85℃Dimensions: 43mm * 21mm * 14mm (L*W*H)
