DC / DC Switching Regulators:

4,104 Products Found

Newark offers an exclusive range of DC-DC switching regulators with improved integration and advanced packaging options. DC-DC switching regulators are essential power management components. 

Unlike linear regulators, switching regulators can step voltage up or down while minimizing power loss as heat. Common topologies include buck (step-down), boost (step-up), and buck-boost converters, each optimized for specific voltage conversion requirements. Modern switching regulators integrate features like synchronous rectification, adaptive frequency control, and protection circuits for overcurrent thermal and undervoltage conditions.

Key applications include smartphones, computers, industrial equipment, and automotive systems, where power efficiency and thermal management are critical. When selecting a switching regulator, engineers consider factors such as input voltage range, output current capability, number of outputs, switching frequency, EMI performance, and solution size.

DC-DC switching regulators offer high efficiency, typically 85-95%, making them ideal for battery-powered devices and energy-sensitive applications. Switching regulators, as their name suggests, control the turning on and off of a switch (transistor) to transfer energy from its input to its output.
