รายละเอียดสินค้าStep up & Down (Buck&Boost) 5-32V to 1.25-32V 4A When the car starts voltage it will be pulled down to 7V or less, or less, of the engine at high speed voltage up to 15V or higher. For work on 12V difficult working appliances, this automatic buck module solves this problem, regardless of the input voltage is 5V or 12V or 32V , the output can be stabilized at 12V . Wide input voltage 5V ~ 32V ; Wide output voltage of 1.25V ~ 35V (with automatic lifting pressure within the operating range, any voltage input can be arbitrarily regulated voltage output); Built- 4A highly efficient MOSFET switch, so the efficiency of up to 94% ; ( LM2577 current only 3A ) Ultra-high switching frequency 400KHz , ripple smaller and smaller. ( LM2577 frequency only 50KHz ) Applications Car regulator, solar photovoltaic, wind power and other voltage instability applications. Technical Parameters: Module : automatic buck module Input range : 3.8V ~ 32V Output Range :1.25V ~ 35V Input Current : 0. 3A (maximum), no-load 18mA ( 5V input, 8V output, no-load is less than 18mA . The higher the voltage, the load current increases.) Conversion 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 Deg.] C ~ 85 deg.] C Dimensions :25mm * 14mm * 48mm (length * width * height)
