This DC-DC Module is based on IC XL6009E1 which is a high-performance step-up switching current (BOOST) module. The module uses the second generation of high-frequency switching technology XL6009E1 core chip that offers superior performance over the first generation technology LM2577. XL6009 replaces the LM2577 module as LM2577 is about to be phased out.
Wide input voltage range of 3V – 32V (optimum operating voltage range is 5 – 32V)
Wide Output voltage range of 5V – 35V (Adjustable using onboard preset)
Built-in 4A MOSFET switches enable the efficiency of up to 94% (LM2577 current is 3A)
The high switching frequency of 400KHz can use a small-capacity filter capacitor that can achieve very good results (LM2577 switching frequency is the only 50KHz)
