This is a DC-DC boost converter step-up power module with high-precision potentiometer, and it uses XL6009E1 with the second generation of high-frequency switching technology as the core chip, its performance is much higher than the first-generation technology LM2577. With high switching frequency of 400KHz, even small-capacity filter capacitors can bring with very nice results, while the ripple is less and the size is smaller.

Specifications:

• Input voltage range: 3V-32V (the best working voltage range is 5-32V)
• Output voltage range: 5V-35V
• With built-in 4A MOSFET switch tube, the efficiency can reach up to 94% (current of LM2577 is 3A only) 
• Ultra-high switching frequency up to 400KH. A small-capacity filter capacitor can achieve very good results, while with smaller ripple and size. (frequency of LM2577 is 50KHz only)
• Dimensions: L * W * H= 43mm x 21mm x 14mm
