Product description: Polol S7V7F5 - step-up/step-down converter - 5 V 1 A - soldered-in connectors.
A small module of the pulse inverter, supplied with voltage from2.7 V to 11.8 V. Output voltage is set to5 V, maximum output current is1 A. The module dimensions are: 9 x 12x 3 mm.The inverter is used to supply circuits operating at 5 V. The circuit has awide range of input voltages, which makes it ideal for battery-powered constructions. Theuse ofS7V7F5ensures stability of power supply during the whole battery discharge cycle. In order to increase reliability, the module is equipped withshort-circuitprotectionand anautomaticpower cut-offcircuitwhen thepermissible operating temperatureis exceeded. The module has soldered-ingoldpinmaleconnectors.
In our offer there is also a set for building a chargerfor smartphones together with an online manual. |
The way of connecting the inverter
The module is extremely simple to use, has three basic outputs:
- VIN- input voltage from 2.7 V - 11.8 V. If the lower module does not switch on, the higher one can damage the system.
- GND- ground potential.
- VOUT- 5 V output voltage.
The way of connecting the inverter
- VIN: input voltage from 2.7 V - 11.8 V. If the lower module does not switch on, the higher one can damage the system.
- GND: ground potential.
- VOUT: 5 V output voltage.
The permitted input voltage range is 2.7 V to 11.8 V. At a lower value, the controller will not switch on. A higher voltage may damage the system.
The output voltage is set to 5 V, but can be up to 5.2 V with no or low load.
The connectors are properly signed on the board.Outputs are 2.54 mm (popular goldpin connectors). The module can be plugged into acontactboard,connected with wiresor soldered intoa dedicated PCB.
Converter output current
The maximum current that can flow through the system depends on the input voltage. This dependence is shown in the diagram below:
The maximum output current as a function of the input voltage.
The efficiency of the inverter depends on the current consumed.
Efficiency of the S7V7F5 inverter
This parameter is particularly important for battery operation when it is important to keep the system running as long as possible on a single charge. The efficiency of the inverter depends on the flowing current and the input voltage (graph below). On average, it is between 85 % and 95 %, allowing the maximum use of battery power.
Voltage jumps (pins)
In electronic circuits the starting current may cause the occurrence of so-called pins, i.e. sudden voltage surges to a value above a set level. If the amplitude of the pins exceeds the permissible value of the regulator, it can be destroyed. Therefore, if the circuit will be supplied with voltage above 9 V or the load will have high inductance, we recommend to solder a capacitor of 33 uF / 25 V or higher as close to the circuit as possible between VIN and GND.
