Description:Show some use more advanced microprocessor voltmeter, boost part by the United States imported boost controller, by utilizing the power MOSFET's on-resistance and eliminates the need for a current sense resistor, maximizing efficiency, efficiency up 96.4%. Imports of high-power low-impedance MOS, big package, high current, high efficiency Schottky, wide thick PCB traces, power efficiency and low temperature rise is guaranteed. Wide voltage, output voltage when the input can be achieved in more than 20V 128W output power. Long-life high-frequency switching power supply for high-capacity low resistance (low ESR) electrolytic capacitor, so that the lower output ripple.Parameters:
Input voltage: 3 ~ 35V DC (Note: The input voltage is less than 4V, onboard voltmeter failure)
Input Current: 9A (max)
Output voltage: 3.5 ~ 35V DC (This board is a step-up board, the output voltage to be> = input voltage)
Output Current: 6A (max)
Output Power: 75W, (when the input voltage is greater than 20V output can reach 128W)
Conversion efficiency: 96.7% (maximum)
Output ripple: 24mV (TYP)
Onboard voltage meter range: 4 ~ 40V, error + -0.1V
Short circuit protection: (limit current 14A). Tips: When access to high-power load, due to the impact of current are just machines Assembly limiting self-locking protection, it is recommended to boot, then access to the load.
Input Reverse Polarity Protection: None (if necessary, please enter the string into the high current diode)
A key switch digital tube light off, a key switch input and output voltage measurements. (On-board voltage indicator "IN" highlight the input voltage, "OUT" highlight the output voltage).Applications:
DIY a power supply, 5V input can be output can be 5-35V adjustable.
Power supply for your electronic device, according to your system can set the output voltage value. For example 3.7V Lithium Mobile Power l do 5V, 7.4V or 12V 19 liters to the laptop power supply.
As car power supply for your laptop, PDA or a variety of digital products supply.
