Product details

What the 300 mA, 5 V fixed output means for your rail

The MAX16956AUBA/V+ is a fixed 5 V output step-down (buck) converter rated for 300 mA continuous output. That 5 V rail is common for powering sensor interfaces, CAN transceivers, or the analog front-end in an automotive or industrial module — no external resistor divider needed to set the voltage.

Switching frequency and package — what drives the layout

At that frequency the switching losses are higher than a 400 kHz part, but the inductor height stays under 2 mm — useful for a low-profile board.

Temperature range and synchronous rectification

The synchronous rectifier (internal low-side FET instead of an external Schottky diode) improves efficiency at light loads — expect 85-90% efficiency at 10 mA load, which matters for always-on modules in a vehicle.
