Product description: D30V30F6 - step-down converter - 6 V 3.3 A - Pololu 4893
A small step-down converter with an output voltage of 6 V and a current efficiency of 3.3 A. Powered by voltage from 6 V to 45 V. 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 D30V30F6 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.

D30V30F6 converter pins.
D30V30F6 converter pins
- VOUT - output voltage 6 V
- GND - system ground
- VIN - input voltage from 6 V to 45 V
- EN - allows you to control the regulator's operation by setting it to low or high
- PG - "Power Good" open-drain 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.
Efficiency of the converter system
The efficiency of the D30V30F6 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.
