Adjustable output voltage & current for flexible applications
XL6009 DC-DC Step-Up Converter (DC-DC Boost Power Supply Module)
- Wide input voltage 3V ~ 32V, optimum operating voltage range is 5 ~ 32V;
- Wide Output voltage 5V ~ 35V;
- Built-4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)
- High switching frequency 400KHz, can use a small-capacity filter capacitors that can achieve very good results, the ripple smaller and smaller. (LM2577 frequency only 50KHz)
