Design challenges
- The extra performance and convenience offered by USB-C makes for more complex circuitry on the PCB
- USB PD via Type-C connectors allows for various power profiles up to 100 W, requires power control switches to be capable of withstanding 20 V or higher
- Low on-resistance is a pre-requisite to minimise energy loss, unwanted thermal challenges, and to comply with USB minimum-voltage regulations
- Designers need to pay careful attention to the trade-off between TVS terminal capacitance (Ct) and the available ESD protection level - to avoid data distortion while ensuring system robustness

恒定電流LED驅(qū)動器
盡管高功率LED需要采用復(fù)雜的驅(qū)動器方案,但絕大多數(shù)應(yīng)用使用電流低于500 mA的LED,可以由線性恒定電流LED驅(qū)動器驅(qū)動。這些驅(qū)動器易于使用、值得信賴、經(jīng)濟(jì)高效且不會影響EMC性能。本文簡要介紹了在實際應(yīng)用中使用恒定電流LED驅(qū)動器時應(yīng)考慮哪些設(shè)計和功率問題。
