Product description: U3V50F24 - 24V 5A step-up converter
A controller that increases the input voltage from 2.9 V to 24 V to an output value of 24 V. The system is able to process a maximum input current of 5 A and its efficiency is 80 - 95 %. The output current is a function of the input voltage, output voltage and inverter efficiency. It is usually the value around the input current of 5 A. Details can be found in the diagrams below.
The U3V50x family offers two versions of inverters with adjustable output voltage:U3V50ALV (4 - 12 V), U3V50AHV(9 - 30 V).Constant voltage versions are also available: 5 V, 6 V, 9 V, 12 V and24 V. All versions of the U3V50x are similar to each other, for easy identification, there is a blank space on the back where you can place your own marker.

Connection
The module has four outputs:
- VIN- input voltage, must not exceed the output voltage.
- GND- ground potential.
- VOUT- output voltage. In case of adjustable version it is selected by means of a potentiometer.
- ENABLE- switches the system into low power consumption state. By default, the pin is pulled up to the VIN supply voltage via a 100 kΩ resistor. This means that if the output is left unconnected, the inverter is switched on by default. In order to put the circuit into standby mode, the low state (below 0.7 V) must be given. In this situation, the module only draws current flowing through the 100 kΩ resistor. This is from 10 µA to 20 µA depending on the connected input voltage.
The connectors are properly signed on the board. The output grid is 5 mm for ARK connectors and 2.54 mm for connectorsgoldpinwhich allow the module to be mounted incontact plateorconnectionby means ofcables.
Soldering connectors for self-soldering are included. You can choose popular goldpins or ARK high-current terminals. Thanks to the thicker PCB layer the terminals do not stick out of the circuit.

Output current and efficiency of the circuit
The efficiency of the inverter depends on the input voltage and the selected output voltage. On average, it ranges from 80 % to 95 %. The output current is a function of the input voltage, output voltage and inverter efficiency. It is usually the value around the input current, i.e. 5 A.
To sum up, the maximum output current is proportional to the ratio of input voltage and output voltage. Additionally, its value may depend on external factors, e.g. temperature or air flow or the heatsink used. If the input current exceeds 5 A, the output voltage will start to fall below the set value.
