Product description: S10V3F9 - 9V 0.3A step-up/step-down 9V - Polyol 2095.

Step-up/step-down converter with 9 V output voltage. Maximum current 300 mA. Power supply 2.5 V - 18 V.

Main features

  1. The output voltage can be higher, lower or equal to the supply voltage (between 2.5 V and 18 V).

  2. Continuous output current is maximum 300 mA - depends on the input voltage (see further details).

  3. Output voltage 9 V with 4 % accuracy.

  4. Integrated temperature protection system.

  5. Small dimensions: 14.6 x 10.16 x 2.54 mm.

The large input voltage range and the stability of the 9 V output voltage with an accuracy of 4 % make the module very well suited as a stabiliser for battery-powered systems. For example, when 9 V is required in a system powered by seven NiMh batteries that are fully charged to 11 V, 8.4 V nominal and only 7.4 V discharged.

In a typical application, the system can provide current up to 300 mA (see further 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- output voltage 9 V.
  • 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 into a contact board, connected with wires or soldered into 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 deliverdepends on: 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.
