Product description: D24V22F12 - Step-down converter - 12V 2.2A - Polyol 2855.
A step-down converter (buck) used to supply power to systems operating at 12 V. The advantage of the system is a wide range of input voltages from 12.7 V to 36 V.. The D24V22Fx module allows for current consumption of up to 2.2 A.
Converter 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. |
| PG | Power quality indicator. Open drain type output that goes into low state when voltage drops below 10 V and high state when voltage reaches over 11 V. An external pull-up resistor must be used to use it. |
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 about 90 % - 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 12 V, the supply voltage should be higher than 13 V. The figures below show the drop-out voltage value for D24V22Fx.
