The S09 module is an automatic DC-DC buck-boost converter that maintains a fixed 12 VDC output regardless of whether the input voltage is higher or lower than this value. It is a compact solution for reliably powering 12 VDC loads from variable-voltage sources, such as Li-ion batteries, lead-acid batteries, or other unstable sources, and is suitable for communication modules, digital radios, industrial motherboards, scale models and aircraft models, household appliances, automotive power supply, and monitoring systems.
The converter accepts an input voltage between 2.5 and 15 VDC and automatically switches between step-up and step-down mode to maintain 12 VDC at the output, with an accuracy of ±0.1 V. The operating frequency reaches 1.2 MHz, conversion efficiency can reach 75%, and output ripple is below 50 mV. The maximum output current is 600 mA, and the quiescent current is below 200 uA, making the module suitable for battery-powered applications where runtime matters.
Among the main features are the 5 connection pads VIN+, VIN-, EN, VOUT+ and VOUT-, the controlled shutdown function via the EN pin, and industrial-grade components for stable long-term operation. Power is supplied through the VIN+ and VIN- pads, with a voltage between 2.5 and 15 VDC, and the module is enabled through the EN pin, which must be driven high for operation, usually by direct connection to VIN+.

Pinout:
| Connector | Pin | Function |
|---|---|---|
| Input pad (VIN) | VIN+ | Positive power input, 2.5 - 15 VDC |
| Input pad (VIN) | VIN- | Input ground (GND) |
| Control pad | EN | Module enable / shutdown, high level for operation |
| Output pad (VOUT) | VOUT+ | Positive output, fixed 12 VDC |
| Output pad (VOUT) | VOUT- | Output ground (GND, common with input ground) |
Usage:
Connect the power source to the VIN+ and VIN- pads, observing polarity, because the module does not have reverse polarity protection.
Connect the EN pin to VIN+ so that the module operates continuously whenever it is powered, or place a switch or transistor between VIN+ and EN to be able to stop and start the output on demand.
Do not leave the EN pin unconnected, because the module remains off or behaves unpredictably without a logic level applied to this pin.
Connect the 12 VDC load to the VOUT+ and VOUT- pads.
Do not apply more than 15 VDC to the input, to avoid damaging the module.
Before connecting the load, measure the voltage between VOUT+ and VOUT- with a multimeter to confirm that the output is 12 V, regardless of the input voltage applied between 2.5 and 15 VDC.
Keep in mind that when the input voltage is much lower than the output voltage, the module operates in step-up mode, and the current drawn from the source can be significantly higher than the current delivered at the output, so choose a source capable of supplying this current.
The module is mounted by directly soldering the SMD pads or by soldering pins with the standard 2.54 mm pitch, for connection to a breadboard or test board.
