Product description: D36V28F9 - Step-down converter - 9V 2.6A - Polyol 3785.
A step-down converter with a voltage supply from 9.8 V to 50 V.The output voltage is 9 Vandits current capacity is 2.6 A. The module dimensions are 20 x 18 mm.
D36V28F9 inverter outputs
| Pin | Description |
|---|---|
| VIN | Input voltage. |
| GND | Mass potential. |
| VOUT | Output voltage. |
| ENABLE | The low-voltage state (below 1 V) will cause the system to go into a low energy consumption state (approx. 10 μA). The pin is pulled to the supply voltage through a 270 kΩ resistor, which makes the system switched on by default. |
| PG | Pin "Power Good" open-drain. It goes into a low state when the output voltage drops below 85 % of its nominal value. If this pin is used, a pull-up resistor, e.g. 10 kΩ, must be connected. |
The board is equipped with the described connectors with a spacing of 2.54 mm. The device can be plugged directly into the contact board, connectedwith wires or solderedinto a dedicatedPCB.

Inverter system efficiency
The efficiency of the inverter is 85% - 95%, it is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter in the case of operation with portable power sources, where time is counted on one charging cycle.
