Design with Step-Up Converter in Cirkit DesignerThe Step-Up Converter (ELC-X0122), manufactured by Custom Thermoelectric, is a DC-DC boost converter designed to increase an input voltage to a higher output voltage while maintaining power balance. This component is widely used in applications where a higher voltage is required from a lower voltage source, such as in battery-powered devices, renewable energy systems, and portable electronics.
This circuit takes a 7V input from a battery and uses a Step Up Boost Power Converter to increase the voltage to a higher, adjustable level. The boosted voltage is then supplied to a power jack for external use.

This circuit is a power management system that steps down a 240V AC input to a lower DC voltage using a buck converter, which then powers a 40W UPS. The UPS is controlled by a rocker switch and is backed up by a battery management system (BMS) connected to three 3.7V batteries in series, ensuring continuous power supply.

This circuit consists of a 12V battery connected to a rocker switch, which controls the input to an XL4015 DC Buck Step-down converter. The converter steps down the voltage to power a DC generator, with the generator's output connected back to the converter to form a feedback loop.

This circuit is designed to provide a stable power supply from various sources. It integrates a solar panel with a solar charge controller to charge a 12V battery, which is then connected to a UPS module for regulated output. The circuit also includes two 12v to 5v step-down power converters to supply 5V power, one of which powers an ESP32 Devkit V1 microcontroller, and a switching power supply to provide an alternative AC to DC conversion input to the UPS module.

The ELC-X0122 has a simple pinout for easy integration into circuits. The table below describes each pin:
| Pin Name | Pin Number | Description |
|---|---|---|
| VIN | 1 | Input voltage pin (connect to the power source) |
| GND | 2 | Ground pin (common ground for input and output) |
| VOUT | 3 | Output voltage pin (connect to the load) |
| EN | 4 | Enable pin (logic HIGH to enable, LOW to disable) |
| FB | 5 | Feedback pin (used for output voltage regulation) |
The ELC-X0122 can be used to power an Arduino UNO from a low-voltage source, such as a 3.7V Li-ion battery. Below is an example circuit and code to enable the converter and monitor its output voltage.
// Define the pin connected to the EN pin of the Step-Up Converter
const int enablePin = 7;
void setup() {
// Set the enable pin as an output
pinMode(enablePin, OUTPUT);
// Enable the Step-Up Converter
digitalWrite(enablePin, HIGH);
// Initialize serial communication for monitoring
Serial.begin(9600);
}
void loop() {
// Simulate monitoring the output voltage (example only)
Serial.println("Step-Up Converter is enabled and powering the Arduino.");
delay(1000); // Wait for 1 second
}

Q: Can the ELC-X0122 be used with a 1.5V battery?
A: No, the minimum input voltage is 2.5V. Using a 1.5V battery will not power the converter.
Q: How do I calculate the feedback resistor values?
A: Refer to the formula in the datasheet:
( V_{OUT} = V_{REF} \times (1 + \frac{R1}{R2}) ),
where ( V_{REF} ) is the reference voltage (typically 1.25V).
Q: Is the ELC-X0122 suitable for powering LEDs?
A: Yes, it can be used to power LEDs, but ensure the output voltage and current are within the LED's specifications.
Q: Can I use the ELC-X0122 for audio applications?
A: Yes, but ensure proper filtering to minimize noise in sensitive audio circuits.
