Piezoresponse force microscopy (PFM) is an effective method for examining ferroelectric materials due to its nanometer-level resolution and high sensitivity, inherited from atomic force microscopy ...

Diodes has launched a series of automotive-compliant synchronous buck converters for delivering up to 3A in automotive point-of-load converters in 3 x 2.8mm TSOT26 packages With 2A and 3A ratings, ...

Limited space requires DC-DC converters designed with thermal performance in mind, advises Timur Uludag of Würth Elektronik. An example of a typical industrial environment with multiple electronic ...

The word “piezo” derives from the Greek word piezein, meaning “to press tightly”. Piezoelectricity refers to a material’s ability to convert mechanical energy (pressing) into electric energy ...

Efficiency prediction for a buck converter at Pulse Width Modulation (PWM) mode is well analyzed. However, not enough attention has been paid to predict efficiency at Pulse Frequency Modulation (PFM) ...

Abstract: A novel methodology for a smooth mode transition between Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes has been proposed for an Inverting Buck-Boost (IBB) and Boost ...

Overall system efficiency is a critical design parameter in battery power systems. It affects both the battery capacity requirement and the end product’s run time. Proper system efficiency and run ...

Piezoelectricity is a material’s capacity to transform mechanical energy (pressing) into electric energy (polarization) and vice versa. The word “piezo” derives from the Greek word piezein, which ...

Abstract: This paper presents a novel pulse width modulation (PWM) and pulse frequency modulation (PFM) control technique to improve the transient response when the converter transition from PFM mode ...
