Description:

This DC-DC Module is the substitute for the LM2577S booster, it 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.

Features:

• 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 efficiency of up to 94% (LM2577 current is 3A)
• High switching frequency of 400KHz, can use a small-capacity filter capacitor that can achieve very good results (LM2577 switching frequency is only 50KHz)
