DC-DC Adjustable Voltage Booster - 4A -V2DC DC Adjustable Voltage Booster 4A V2 Description: By adopting XL6009 ic (superior to LM2577 IC) after configuration, this module is capable of generating negative input voltage to positive output voltage by boosting. The XL6009 built in N channel power MOSFET and fixed frequency oscillator, current mode architecture results in stable operation over a wide range of supply and output voltages. Features: * Readable voltage by LED display * Wide 5V to
