Product details

The Maxim MAX16956AUBD/V+ is a step-down (buck) switching regulator with a fixed 5 V output, rated for 300 mA continuous output current. It integrates a synchronous rectifier, which improves efficiency at light loads compared to a diode-based buck — a useful trait for always-on automotive body controllers or industrial auxiliary rails. The 2.1 MHz switching frequency lets the designer use a physically small inductor, saving board area in space-constrained modules.

The supplier device package is 10-uMAX-EP.

It is ROHS3 compliant, which satisfies the material restriction requirements for most global markets including automotive.

Frequently asked questions

Is MAX16956AUBD/V+ RoHS compliant and suitable for automotive?

The part is ROHS3 compliant. With an operating temperature range of -40°C to 125°C and a wide input voltage range of 3.5 V to 36 V, it is suited for automotive under-hood and body-control applications.

What are the direct alternatives or equivalents for MAX16956AUBD/V+?

Maxim offers other fixed-output buck converters in the same package family, but the evidence does not list a specific pin-compatible alternate. For a second-source option, review the Maxim 5 V fixed-output, 300 mA buck family in the 10-uMAX-EP package — parametric differences in switching frequency or enable logic may apply.

Does MAX16956AUBD/V+ require any external components for stable operation?

Like any switching regulator, it requires an input capacitor, an output capacitor, and an inductor sized for the 2.1 MHz switching frequency and 300 mA output. The datasheet provides recommended component values and layout guidelines.
