Description S9V11F3S5 - step-up/step-down converter - 3.3 V 1.5 A - Pololu 2872
The converteris used to supply circuits operating at 3.3 V. The circuit has a wide range of input voltages, which makes it ideal for battery-powered designs. Application of S9V11F3S5provides stability of power supplyduring the entire cycle of battery discharge. In order to increase reliability, the module is equipped with short-circuit protection and automatic power cut-off when the permissible operating temperature is exceeded.
We also offer a set to build asmartphone charger with on-line manual. |

How to use
The module is very simple to use, it has three basic leads:
- VIN- input voltage from 3 V to 16 V. With lower voltage module will not turn on, higher can damage the chip.
- GND- Ground of the system.
- VOUT- output voltage of 3.3 V.
How to use
- VIN: - input voltage from 3 V to 16 V. With lower voltage module will not turn on, higher can damage the chip.
- GND: - Ground of the system.
- VOUT: - output voltage of 3.3 V.
Additional pins:
- EN- Enable input. It switches on the circuit after applying voltage above 0,8 V. It is connected through voltage divider withVIN, so it cuts off the power at VIN below the set value.
- PG- voltage quality indicator. An open-drain type output, it sets low when the power drops below 90% of the nominal voltage, also when theENpin is in the low state. Returns to the high state when the mod 95 % is exceeded. Has high impedance, requires a pull-up resistor.
- SEL- output can be driven from 1.1 V to 16 V to change theVOUToutput to 5 V. SettingSELlow or unconnected setsVOUTto 3.3 V. To set to 5 volts permanently, solder a wire as shown below.

The allowable input voltage range is from 2 V to 16 V. The regulator will not turn on at a lower value. A higher voltage may damage the circuit.
The connectors are properly signed on the board.The pinout is 2.54 mm (goldpin connectors). The module can be plugged into thecontactboard, connected bywiresor soldered into a dedicated PCB.
Maximum output current as a function of input voltage.
Output current
The maximum current that can flow through the system depends on the value of the input voltage. This relationship is shown in the diagram below:
Efficiency
This parameter is especially important with battery power supply, when it is important for the system to work as long as possible on a single charge. The efficiency of the converter depends on the current flowing and the input voltage (graph below). On average, it is between 85% and 95%, which makes it possible to use practically the maximum energy from the battery.
Efficiency of the converter depending on the current consumed.
Voltage jumps (pins)
In electronic circuits, the starting current may cause so-called spikes, sudden jumps in voltage to a value above a specified level. If the amplitude of the spikes exceeds the allowable value of the regulator, the regulator can be destroyed. Therefore, if the circuit will be supplied with voltage above 9 V or the load will have high inductance, we recommend soldering a capacitor of 33 µF / 20 V or higher as close as possible to the circuit between VIN and GND.
