XL6009 is a high-performance boost (BOOST) module with a 4A switching current.
This module uses XL6009E1, a second-generation high-frequency switching technology,
as the core chip, with performance far exceeding that of LM2577, the first generation technology.
The XL6009 boost module has lower cost and superior performance.
4. With a high switching frequency of 400KHZ, a small capacity filter capacitor can achieve very good results. Compared
to LM2577, the ripple is smaller and the volume is smaller (LM2577 frequency is only 50KHz).
