brand new and high quality.
brand new and high quality.
Quantity:1pc
Size : 20mmX20mmX5mm/0.78”X0.78”X0.19”(inch) (approx)
Module Properties: non-isolated boost
Rectification: non-synchronous rectification
Input voltage: 2.5V-6V
Output voltage: 4V-12V (adjustable)
Output Current: 1000mA (Max)
Conversion efficiency: 92% (the highest)
Switching frequency: 1MHz
Output ripple: 20mV (max)
Load Regulation: 0.5%
Voltage Regulation: 2.5% Note: Formula output :VOUT = (R1/R2 +1v) * 0.6V Default resistance : R1 = 150K R2 = 20K (unit:ohm) By adjusting the voltage of this formula , which is calculated by the formula resistors , R1 or R2 , replace the resistor can be calculated on the desired output voltage. The R1, R2 can be removed and replaced with other resistance. Example: I want the output voltage is 8V, then want to replace R1 ,Then 8 = (R1/20K +1) * 0.6, calculate R1, put on it.
