Step-Up/Step-Down Voltage Regulator S13V15F5 - 5V 1,5A - Pololu 4084

A small step-up / step-down converter module generating 5V output voltage and 1.5A current capacity. The converter can be supplied with voltage from 2,8V to 22V. Step-up / step-down converters are used in projects where there are voltage variations due to the use of batteries, for example. The efficiency of the regulator is between 85% and 95% and can deliver between 1 A and 2 A depending on the input voltage. The module has undervoltage lockout, output overvoltage protection, and overcurrent protection. An over-temperature shutdown function also helps prevent overheating damage, and a soft-start function limits the inrush current and gradually increases the output voltage during startup.

The inverter is equipped with three pinouts labeled: input voltage (VIN), ground (GND), and output voltage (VOUT). The input voltage (VIN) is responsible for supplying the inverter with power from 2.8 V to 22 V. The VOUT connector is the 5 V output from the inverter. There is a goldpin solder strip included in the package. With it you can plug module directly into contact board.

The efficiency of an inverter is (power output) / (power input), it is an important measure of its performance, especially when it comes to battery life or heat generation.

The maximum output current achieved by the controller depends on the input voltage and other factors such as ambient temperature, airflow, and heat absorption. The chart shows the maximum output currents that the controller can deliver continuously at room temperature, without airflow or additional heat dissipation.

The resting current is the current that the inverter uses to power itself, and the graph shows this as the input voltage.
