Product description: Polol D24V25F5 - step-down converter - 5V 2.5A.

A step-down converter (buck) used to supply power to systems operating at 5 V. The advantage of the system is a wide range of input voltages from 6 V to 38 V.

D24V25F5 module allows for current consumption up to 2.5 A. In our offer there is also a step-down system D24V50F5 withmaximumoutput current up to 5 A.


Pin Description
VIN Input voltage from 6.0 V to 38 V.
GND Mass potential.
VOUT Output voltage.
ENABLE If a low voltage of less than 0.6 volts is applied), the system will go into a low power consumption state (approx. 20 μA). The pin is pulled to the supply voltage through a 100 kΩ resistor, which makes the system switched on by default.

System efficiency

Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter when working with portable energysources(batteries and accumulators), where the time of operation on one charging cycle counts. The efficiency of this pulse system is about 85 % - 95 %.

Voltage drop-out

The parameter referred to in the documentation asvoltag drop-outthennecessary for the proper functioning of the system,minimum difference between input and output voltage.For example, if the drop-out is 1 V and the desired output voltage is 5 V, the supply voltage should be higher than 6 V. The figures below show the drop-out voltage value for D24VxFx inverters.

Works as it should. Very compact. The fairly high price may be a downside.
