Product description: D36V28F7 - Step-down converter - 7.5V 2.6A - Polyol 3784.
A step-downconverterwith 7.5 V output voltage and capacity from 2 A to 3.7 A, typical2.6 A.It is powered from 8V to 50 V.The board dimensions are 20 x 18 mm.
D36V28F7 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 module is equipped with the properly described connectors, which are arranged at a distance of 2.54 mm. The device can be plugged directly into the contact board, connectedwithwires or soldered into a dedicatedprinted circuit board.

Inverter system efficiency
The system has an efficiency of about 85% - 95%. Efficiency 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 the time of operation on one charging cycle counts.
