Product description: Polol D24V25F6 - step-down converter - 6 V 2.5 A.
A step-down converter (buck) used to power systems operating at 6 V. The advantage of the system is a wide range of input voltagesfrom 7 V to 38 V. D24V25F5 module allows for current consumption up to 2.5 A.
Outputs
| Pin | Description |
|---|---|
| VIN | Input voltage. |
| 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. |
The connectors are properly signed on the board. Outputs are 2.54 mm (popular goldpin connectors). The module can be plugged into acontactboard,connected with wiresor soldered intoa dedicated PCB.
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 about85% to 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.
