DC-DC Boost-Buck converter (Step Up and Step Down)

Which makes this module particularly useful is its ability to operate as a step-up or step-down converter. The output voltage is adjusted with a high-precision potentiometerand 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:3.5V-30VOutput voltage range: 5V – 30VA 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= 48mm x 25mm x 12mm
