The XL6009E1 DC-DC Step-Up Boost Power Supply Module is a high-performance adjustable voltage regulator designed to boost lower input voltages into a stable, higher output voltage. Powered by the advanced XL6009E1 switching regulator chip, it operates at a fast 400kHz switching frequency to efficiently step up an input voltage range of 3V to 32V DC to a user-defined output range of 5V to 35V DC. Featuring a high-precision multi-turn potentiometer for fine voltage adjustments, this compact board supports an impressive peak switching current of up to 4A, making it an essential power converter for battery-operated devices, solar charging systems, and portable electronic builds.
