The XL6009 is a high-performance 400KHz 4A switch currency step-up (BOOST) module featuring advanced high-frequency switch technology as its core component. Its performance significantly surpasses standard options. It supports a wide input voltage range of 3V to 32V, with an optimum operating voltage range of 5V to 32V, and offers output voltages from 5V to 35V. Equipped with 4A high-efficiency MOSFET switches, the efficiency of the XL6009 can reach up to 94%. With an ultra-high switch frequency of 400KHz, even small-capacity filtering capacitors achieve excellent results, resulting in reduced ripple compared to lower-frequency options. This module includes a 0.1uF high-frequency bypass capacitor to effectively filter out high-frequency noise. Product Dimensions: 4.65 x 3.23 x 1.22 inches.
