Description

Product description: S9V11F5 - step-up/step-down converter - 5 V 1,5 A - Pololu 2836

The converter is used to supply circuits operating at 5 V. The circuit has a wide range of input voltages, which makes it ideal for battery-powered designs. Application of S9V11F5 provides stability of power supply during 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 a smartphone charger with on-line manual.

Directions for use

The module is very simple to use, it has three basic pins:

VIN - input voltage from 2 V to 16 V. With lower voltage module will not turn on, higher can damage the system.
GND - ground potential.
VOUT - output voltage of 5 V.

Permissible input voltage range is from 2 V to 16 V. If the value is lower, the regulator will not switch on. Higher voltage can 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. The pinout is 2.54 mm (goldpin connectors). The module can be plugged into a contact board, connected via wires or soldered into a dedicated PCB.

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:

Maximum output current as a function of input voltage.

Efficiency of the converter

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 flow and the input voltage (the graph below). On average, it is on the level of 85-95%, which allows to use practically maximum energy from the battery.

Voltage jumps (pins)

In electronic circuits, the starting current can cause so-called spikes, which are sudden spikes in voltage to a value above a predetermined level. If the amplitude of the spike exceeds the regulator's allowable value, the regulator may be destroyed. Therefore, if the circuit will be supplied with voltage above 12 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.
