XL6009 is a 4A switch current high performance boost ( BOOST ) module. This module uses the second-generation high-frequency switching technology XL6009E1 as the core chip, and its performance far exceeds that of the first-generation technology LM2577 . The XL6009 booster module has lower cost and better performance, and the LM2577 module is about to be eliminated.

Features :

1. The performance is much higher than LM2577.
2. Non-isolated Boost converter.
3. It has a non-synchronous rectifier.
4. Small and Handy voltage regulator module.

Applications:

1. High-power LED driver
2. Lithium battery(or lead accumulator) charge
3. Vehicle-mounted power supply
4. Low voltage system power supply
5. 6V, 12V, 14V, 24V battery charge
6. On-board laptop power supply
7. regulated power supply
8.Low voltage power supply system
