Product description: D36V50F7 - 3.3 V 9.5 A step-down converter
Astep-downconverter with a 7.5 V output voltage, operateson an input voltage in the range from 4.5 V to50 V. Thecurrent capacity isfrom 4.5 A to 9.5 A.The module operates a fairly wide range of input voltages from 4.5V to50 V, theminimumvalue ofthe input voltage is dependent on the drop-out voltage.

The system is protected by reversal protection up to 40 V, under-voltage and over-voltage output protection and over-current and short circuit protection.
D36V50F3 inverter outputs
| Contact | Description |
|---|---|
| VOUT | Output voltage. |
| GND | Mass potential. |
| VIN | Input voltage. |
| VRP | Access to the input voltage after activation of the voltage reversal protection. It can be used as a power supply output for other devices or as a VIN without reversal protection. |
| EN | I can put the inverterat standstillby reducing the voltage at the EN contact below 1.2 V, and can also take it out of this state by increasing the voltage at the EN contact above 1.35 V. |
| PG | Power Good, an open drain output that decreases when the output voltage increases by more than 20% and the output voltage decreases by more than 10%. |
The connectors are properly signed on the board. Converters can be plugged into thecontactboard,connected usingconnectionwires or soldered into the PCB.

At the customer's request, we can supply a system with soldered goldpin connectors. For this purpose, please leave the information in the commentary to the order. |
Voltage drop-out
DVoltag rop-outedeterminestheminimumdifferencebetween the input and output voltagesrequired forproper operation of the inverter.Assuming thatthedrop-out is 1 V and the output voltage we want to get is 5 V, the supply voltage should be higher than 6 V. The following diagrams show the drop-out value for D36V50Fx inverters. The minimum voltage required including the dropout parameter is alsospecified.

System efficiency
The inverter efficiency parameter is the ratio of output power to input power. It is an important parameter when working with portable energy sources such as batteries andaccumulators, wherethe operating time on one charging cycle iscrucial. The diagrams below show the efficiency parameter in D36V50Fx.

Output current
The output current is dependent on theinput voltageand factors such asambienttemperature,airflowandheatabsorption.The graphs below show the maximum output currents of the D36V50F1x at room temperature, still air and without additional heat traps.
Maximum output current.
Standby current
Currentonlyusedto supplythe module itself, the diagrams below show the values of this parameter current for all systems in the D36V50F1x series. Setting the voltage below 1.2 V at the EN contact allows the inverters to be put into a low current state.
The graph shows the idle current for all systems in the D36V50F1x series.
