D30V30MAx Fine-Adjust Voltage Regulators

The D30V30MAx family of buck (step-down) voltage regulators are compact, adjustable-output members of the broader D30V3x line of synchronous regulators. They generate lower output voltages from input voltages as high as 45 V and can typically support continuous output currents between 1 A and 4 A, depending on the input voltage and output voltage. They also have very low dropout voltages.

1At 30 V in. Actual achievable continuous output current is a function of input and output voltages and is limited by thermal dissipation.
2Operating voltage must be higher than the set output voltage and is subject to dropout voltage considerations.

The output voltage is precision adjustable through an 11-turn potentiometer, and each version is available with or without an adjustable low-voltage cutoff (also set through a precision 11-turn potentiometer).

The regulators have reverse voltage protection up to 40 V, input under-voltage lockout, over-current protection, and short-circuit protection. A thermal shutdown feature also helps prevent damage from overheating and a soft-start feature limits the inrush current and gradually ramps the output voltage on startup.
