Description
Product description: D36V28F5 - Step-down converter - 5 V 3.2 A - Polyol 3782.
A step-downconverter(bulck) with 5 V output voltage and capacity from 2.5 A to 4 A, typical3.2 A.Powered from 5.3 V to 50 V. The board dimensions are 20 x 18 mm.
D36V28F5 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.There are described connectors on the board at a distance of 2.54 mm. The converter can be plugged directly into thecontactboard, canbe wired orsoldered intoa dedicated printed circuit board.
D36V28F5 converter.
Inverter system efficiencyEfficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is an important parameter in the case of operation with portable energy sources, where time is counted per charge cycle. The efficiency of this system is about 80% - 90%.
