Description

The Step-Down Converter D30V3x is a buck-type voltage regulator module that lowers output voltages from input voltages up to 45 V. It offers significantly higher efficiency compared to linear regulators, especially when there is a large difference between input and output voltages. This converter can handle continuous output currents ranging from 1 A to 4 A, depending on the input and output voltages.

The module allows for output voltages from 4.2 V to 15 V thanks to an 11-turn potentiometer. It also features a built-in potentiometer for adjusting the cut-off voltage.

The converter is equipped with protection against reverse voltage up to 40 V, an input undervoltage lockout, and protection against overcurrent and short circuits. Additionally, the over-temperature protection feature prevents damage from overheating, while the soft start function limits inrush current and gradually increases output voltage during startup.
