可以先看一下第二篇，大致看一下这个片子的情况，然后来学习。 先总结：COT 是一种基于事件触发、以“反馈电压掉下来就导通”的极快响应型控制方式，非常适合快速响应、高频、小尺寸降压芯片。 COT：恒定导通时间 COT（Constant On-Time，恒定导通时间）控制 ...

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 ...

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 ...

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 ...

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) ...

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 ...

eSR-Niagara-Bu-dm-ref-1.62-3.63-0.8-2.5.01_TSMC_55_uLP is a DC/DC converter in TSMC 55uLP, flexible and readily re-targetable toward any sub micron CM ...
