Product details

Wide-input buck for industrial auxiliary rails

The MAX5035BUSA+T is a step-down (buck) switching regulator that delivers a fixed 5 V output at up to 1 A from a DC input spanning 7.5 V to 76 V.

1 A output — sized for sensor and MCU rails

At 1 A, the MAX5035BUSA+T is sized for powering a small microcontroller, a few op-amps, a sensor cluster, or a low-power wireless module. The fixed 5 V output suits legacy logic families, 5 V sensors, and many industrial analog front-ends.

Temperature grade and deployment environment

Rated for 0°C to 85°C ambient, this part fits commercial and indoor industrial environments — office equipment, factory-floor control cabinets with climate control, and telecom equipment in conditioned shelters.

Lifecycle and sourcing posture

The MAX5035BUSA+T carries an Active lifecycle status with ROHS3 compliance.

Frequently asked questions

How does MAX5035BUSA+T compare to LM2596 for a 5V 1A design?

Both are non-synchronous buck regulators with a similar output current and fixed 5 V option. The MAX5035BUSA+T accepts a higher maximum input (76 V vs 40 V for the LM2596), making it a better fit for 48 V or 72 V buses. The LM2596 typically switches at 150 kHz versus 125 kHz for the MAX5035, so the magnetics are comparable in size. The MAX5035 comes in an 8-SOIC package; the LM2596 is available in TO-220 and TO-263. For a 5 V 1 A design on a 24 V or lower rail, either works; for a 48 V or 72 V rail, the MAX5035 is the safer choice.

Is there a pin-compatible alternative to MAX5035BUSA+T with higher output current?

Within the MAX5035 family, the MAX5035AUSA+T and MAX5035CUSA+T share the same 8-SOIC pinout and input voltage range but offer output voltages of 3.3 V and 12 V respectively, not higher current. For higher output current in a similar footprint, consider the MAX5037 series (up to 2 A) in a different package — verify pin compatibility against your layout.
