Many of us know that we can dim and brighten an LED using the PWM on an Arduino, but a closer inspection with an oscilloscope still shows 5V peaks that would be dangerous to a 3.3V circuit.

Besides generating multiple outputs, the buck converter is configurable to operate as an inverting buck-boost converter, essentially providing a voltage step-up function. In addition, designers can ...

The theory of buck-boost converter operation. How to build buck-boost converters using the SLG47105. Discover real-life examples where these devices can be used. DC-DC converters are widely used ...

Figure 2 The buck-boost regulator circuit produces a negative output voltage.. Figure 3 shows a low-cost buck-boost converter based on the LM5010 buck-regulator IC that converts a 10 to 50V positive ...

Figure 3 presents a circuit with an LT8350S buck-boost switching regulator. This device can carry up to 6-A switch current and has an input voltage range of 3 to 40 V.
