Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...

This is a 5V to 12V DC-DC step-up (boost) converter circuitry that is especially ideal for the USB powered applications. First of all a USB port has two current supply modes. Before detecting the ...

We all know that the reason the electrical system uses alternating current is because it’s easy to step the voltage up and down using a transformer, a feature which just isn’t possible with a DC ...

Austriamicrosystems has expanded its family of step-up dc-dc converters with the introduction of the AS1325, a high-efficiency step-up part with a fully integrated synchronous rectifier. With a 96% ...

This state-of-the-art synchronous buck-boost converter operates in either buck mode or boost mode, which enables high efficiency over wide input voltage range. The parallel of MOSFETs along with ...

LCD and organic-LED displays for handheld portable equipment sometimes have problems with runaway outputs from high-voltage boost converters damaging displays. LCD and organic-LED displays for ...
