Description
A step-down converter (buck) used to power systems operating at 9 V. The advantage of the system is a wide range of input voltages from 11 V to 40 V..
The D24V150F9 allows for a current draw of up to 15 A. In our offer there are also step-down systems from the seriesD24VxFywith different voltages and maximum currents.
Exits
| Pin | Description |
|---|---|
| VIN | Input voltage from 11 V to 40 V. |
| GND | Mass potential. |
| VOUT | Output voltage. |
| ENABLE | If a low-voltage state below 1 volt is given), the system will go into a low energy consumption state (approx. 10 μA). The pin is pulled to the supply voltage through a 100 kΩ resistor, which makes the system switched on by default. |
| PG | Energy meter. Open-drain output going into low state when voltage drops below 85 % of nominal or rises above 115 %. An external pull-up resistor shall be used to use this pin. |
| MOD | Mode pin, internally pulled to a low state, which selects fixed frequency mode. Pulling to a high state reduces the idle current (while increasing efficiency) at low loads (several milliamps). This function is available when the input voltage is significantly higher than the output voltage. |
Connectors are properly signed on the board. Outputs Raster is 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 80 % - 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.
