Product description: D30V30F12 - step-down converter - 12 V 2.8 A - Pololu 4896
The D30V30F12 step-down converter from Pololu is a device that allows you to reduce the input voltage in the range from 12 V to 45 V to a constant output voltage of 12 V. The module can deliver a maximum continuous output current of up to 2.8 A with typical efficiency of 80% to 95% , depending on the input voltage and load. Thanks to the use of switching mode converter (SMPS) technology, the module is much more effective than traditional linear regulators , especially with large differences between the input and output voltage. The regulator has built-in reverse polarity protection up to 40 V, protection against low input voltage, protection against overcurrent and short circuit, as well as a thermal shutdown function. The D30V30F12 converter is equipped with a soft start function that limits the starting current and gradually increases the output voltage. Thanks to its compact dimensions of 17.8 x 20.3 x 9 mm and the pinout layout compatible with breadboards, the module is easy to integrate into various projects.

D30V30F12 converter pins.
D30V30F12 converter pins
- VOUT - output voltage 12 V
- GND - system ground
- VIN - input voltage from 12 V to 45 V
- EN - allows you to control the regulator's operation by setting it to low or high
- PG - open-drain "Power Good" pin. Goes low when the regulator output voltage increases more than 7.5% above or drops more than 9% below the nominal voltage (with hysteresis). If this pin is used, a pull-up resistor must be connected.
The set includes goldpin strips for self-soldering. Using them, the converter can be connected directly to the breadboard .
Efficiency of the converter system
The efficiency of the D30V30F12 step-down converter is a key parameter, especially when saving energy or minimizing heat generation is important. Typical efficiency is 80% to 95% , depending on the input voltage, output voltage and load. Thanks to the use of pulse converter technology, the device effectively minimizes energy losses compared to linear regulators, making it ideal for applications requiring high efficiency.

Maximum achievable output current
The maximum output current that the D30V30F12 converter can deliver depends on the input voltage , as well as other factors such as ambient temperature, air flow and heat absorption. The graph shows the maximum output currents that the controller can deliver continuously at room temperature, without air flow and additional heat dissipation. The converter is designed to ensure stable operation and protection against overheating, which increases its reliability in demanding conditions.
