A low-current, negative high-voltage is required to bias sensors in advanced driver assistance systems, ultrasonic transducers for sonar applications, and communications equipment. Flyback, Cuk, and ...

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 ...

Many portable devices use LCD displays. These displays need large positive and negative power supplies, but most mobile devices have power rails at 5 V, 3.3 V or even lower. Thus, the challenge is not ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...
