Design with Switching step-up voltage regulator in Cirkit DesignerA switching step-up voltage regulator, also known as a boost converter, is an essential electronic component that efficiently increases a lower input voltage to a higher output voltage through the use of inductors, diodes, and capacitors. This type of regulator is widely used in battery-powered devices, portable electronics, and LED drivers where a consistent and higher voltage output is necessary from a lower voltage source.
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 Li-ion battery connected to a step-up power module through a rocker switch, which boosts the voltage to power a ring of copper gauge with an aluminum frame. The rocker switch allows the user to control the power flow from the battery to the step-up module, which then supplies the boosted voltage to the copper ring.

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 for power management, featuring buck and boost converters for voltage adjustment, and linear regulators for stable voltage output. It includes LEDs for status indication, and terminal blocks for external connections.
Open Project in Cirkit Designer| Parameter | Specification | Notes |
|---|---|---|
| Input Voltage (Vin) | 2.0V to 15V | Minimum and maximum input voltage |
| Output Voltage (Vout) | 2.5V to 35V | Adjustable via external components |
| Switching Frequency | 50kHz to 1MHz | Varies by specific model |
| Maximum Output Current | 1A to 3A | Depends on input voltage and heat dissipation |
| Efficiency | Up to 95% | Varies with load and input voltage |
| Pin Number | Name | Description |
|---|---|---|
| 1 | GND | Ground connection |
| 2 | VIN | Input voltage supply |
| 3 | SW | Switch node, connects to inductor |
| 4 | FB | Feedback pin, sets output voltage |
| 5 | EN | Enable pin, turns regulator on/off |
| 6 | VOUT | Regulated output voltage |
Q: Can I adjust the output voltage? A: Yes, by changing the resistor values in the feedback network connected to the FB pin.
Q: What is the maximum input voltage I can apply? A: The maximum input voltage is typically 15V, but always refer to the specific model's datasheet.
Q: How do I enable or disable the regulator? A: Apply a high signal to the EN pin to enable and a low signal or ground to disable the regulator.
// Example code to control a switching step-up voltage regulator's EN pin using Arduino UNO
const int enablePin = 7; // Connect the EN pin of the regulator to digital pin 7
void setup() {
pinMode(enablePin, OUTPUT); // Set the enable pin as an output
}
void loop() {
digitalWrite(enablePin, HIGH); // Enable the step-up regulator
delay(5000); // Wait for 5 seconds
digitalWrite(enablePin, LOW); // Disable the step-up regulator
delay(5000); // Wait for 5 seconds
}
Remember to adjust the pin number in the code to match your actual setup. The above code simply turns the regulator on and off every 5 seconds.
