Product description: S10V2F12 - 12V 0.2A step-up/step-down 12V - Polol 2096.
Step-up/step-down converter with 12 V output voltage. Maximum current 200 mA. Power supply 2.5 V - 18 V.
Main features
-
The output voltage can be higher, lower or equal to the supply voltage (between 2.5 V and 18 V).
-
Continuous output current is 200 mA maximum - depends on the input voltage (seefurther details).
-
Output voltage 12 V with 4 % accuracy.
-
Integrated temperature protection system.
- Small dimensions: 14.6 x 10.16 x 2.54 mm.
The large input voltage range and the stability of the 12 V output voltage with an accuracy of 4 % make the module very well suited as a stabiliser for battery-powered systems. For example, when 12 V is required in a system powered by three li-pol targets, where a fully charged packet exceeds 12 V and reaches 11.1 V nominal.
In a typical application, the system can deliver a current of up to 300 mA (seebelowfor details).The controller is equipped with temperature protection, but has no protection against short circuit and reverse power connection.
Outputs
The module has four outputs:
- VIN- input voltage from 2.5 V - 18 V. If the lower module does not switch on, the higher one can damage the system.
- GND- ground potential.
- VOUT- 12 V output voltage.
- SHDN- switching off the system - giving a low state, makes the system go into a low power consumption state. The output is pulled to the VIN via a 10 kΩ resistor, which makes the system switched on by default.
Connectors are properly signed on the board. Outputs Raster is 2.54 mm (popular goldpin connectors). The module can be plugged intoa contact board, connected withwires or solderedinto a dedicated PCB.
System efficiency
Efficiency is defined as the ratio of input power to output power (Pout/Pin). 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 70-80 %, which allows the maximum use of battery power.
Output current
The maximum current that the system can deliverdependson: input voltage and operating temperature. The dependence of the maximum current consumption on the input voltage is shown in the figure below. If the operating temperature reaches too high a value, the module will automatically disconnect the power supply.
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 11 V or the load will have high inductance, we recommend to solder a capacitor of 33 uF / 25 V or higher as close as possible to the circuit between VIN and GND.
