Step up and Step Down Modules

This module is a non-isolated step-up (boost) voltage converter featuring adjustable output voltage and high efficiency. Description: XTW6009 is a 4 a switch current high-performance step-up (BOOST) module. The XL6009E1 module uses the second generation of high frequency switch technology as the core chip, LM2577 performance far beyond the first generation of technology. XL6009 booster module cost is lower, performance is more outstanding, LM2577 module will be eliminated. If the input or output current is more than 2A (need to plug heat sink), if the output power is higher than 15 W, advise to add the heat sink.
