12V Step-Up/Step-Down Voltage Regulator S18V20F12 uses SEPIC conversion for inputs above or below 12 V. An ENABLE input and integrated protection support battery-powered circuits. More product details

Product Description

The 12V Step-Up/Step-Down Voltage Regulator S18V20F12 from Pololu produces a fixed output from a supply that can be above or below the target voltage. Its SEPIC topology suits battery-powered circuits whose supply crosses the required output level during discharge. The board is intended for developers integrating a regulated 12 V supply into their assemblies. Connections use VIN, GND and VOUT, while ENABLE provides a low-power state. Solder connections accommodate terminal blocks, pin headers or directly attached wires.

Highlights

Input voltage from 2.9 to 32 V; recommended maximum 30 V.
Fixed 12 V output with 4% accuracy.
Typical maximum output current of 2 A with input voltage close to 12 V.
Integrated reverse-voltage, over-current, over-temperature and under-voltage protection.
Typical efficiency of 80% to 90%, depending on operating conditions.

Technical Features

Converter topology: SEPIC with step-up and step-down operation.
Recommended input voltage range: 3 to 30 V.
Output voltage: fixed 12 V, accuracy 4%.
Typical maximum output current: 2 A with input voltage close to output voltage.
Efficiency: typically 80% to 90%.
Quiescent current: typically about 1 mA, maximum 5 mA.
Connections: VIN, GND, VOUT and ENABLE; 2.54 mm header pitch and 5 mm terminal block pitch.
ENABLE shutdown threshold: below 0.7 V; sleep current 10 to 20 µA per volt of input voltage.
Dimensions: 43 × 21 × 10 mm; weight: 7.5 g.
Mounting: four approximately 2.18 mm diameter holes for M2 or #2 screws.

Application Areas

Powering 12 V circuits from battery packs whose voltage moves above and below 12 V during discharge.
Building prototypes with a regulated 12 V supply and 2.54 mm connections.
Providing an externally switchable supply for battery-powered electronics through ENABLE.

Notes

32 V is the absolute input voltage limit; reverse-voltage protection is limited to 30 V. Input voltage spikes must be considered.
2 A is not an unconditional continuous-current rating. Input voltage, ambient temperature, airflow and heat dissipation determine the available current.
The board can become hot enough to cause burns during operation. Thermal shutdown typically activates at 165 °C.
The output remains capacitively coupled to the input even when ENABLE is disabled. Leave ENABLE disconnected when the shutdown function is not required.
