Looking for a quick and easy way to boost 5VDC to 24VDC ... The module uses the Texas Instruments LM2577 step up voltage regulator, and incorporates the required inductor and adjustment preset on the board. Input voltage ranges from 3.5 to 30 Volts, and output can be adjusted from 4 to 30 Volts, as long as the output is not set to more than 3 times the input voltage. Step Up (Boost) Switching Converters Regulators Step up switching converters, also called boost switching regulators, provide a higher voltage output than the input voltage. The output voltage is regulated, as long as the power draw is within the output power specification of the circuit. Many of our step up switching regulators are designed for driving strings of LEDs.
