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.
If your step-up/boost application is not power intensive (IOUT < 0.5A), you may prefer a different power conversion technology for boost applications: charge pumps. View our charge pump IC family.
