Switching Regulators
Our high-efficiency DC-DC switching regulator ICs generate less heat, consume less current and require less board space than other solutions, enabling more robust operation and longer battery life. Switching regulator circuits use a power switch, an inductor, and a diode to transfer energy from input to output. The basic components of the switching circuit can be rearranged to form a step-down (buck) converter, a step-up (boost) converter, or an inverter (flyback). Feedback and control circuitry can be added to regulate the energy transfer and maintain a constant output. Our wide selection of DC-DC converters offer high switching frequencies, very efficient internal switching elements, wide input voltage ranges, and built-in circuit protection to support a broad range of applications.

4V to 42V, 100mA, Compact Step-Down Power Module
MAXM17532The MAXM17532 is a step-down DC-DC power module built in a compact uSLICTM package. The MAXM17532 integrates a controller, MOSFETs, an inductor, as well as the compensation components. The device operates from an input voltage of 4.0V to 42V, supports an adjustable output voltage from 0.9V to 5.5V, and supplies up to 100mA of load current. The high level of integration significantly reduces design complexity, manufacturing risks and offers a true “plug and play” power supply solution, hence reducing the time-to-market.
