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.

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.
