These power-hungry features have created the need for users to charge their mobile phone batteries frequently and quickly. Legacy inductor-based chargers are still widely used in mobile applications, but the high heat from induction charging limits higher charging power for the battery. These chargers are unable to satisfy users who require fast charging. Switched-capacitor (SC) direct charging has been recognized as a good replacement for inductor-based charging, because of its higher efficiency and lower heat dissipation. 1691155967957710813422 PSP 242.2 KB None None documents None 1691155967957710813422 /docs/en/application-note/AN13732.pdf 242152 /docs/en/application-note/AN13732.pdf AN13732 documents N N 2023-08-04 AN13732: PCA9482UK 6 A 2:1, 1:2, and 1:1 Mode Switched Capacitor Direct Charger Application Note /docs/en/application-note/AN13732.pdf /docs/en/application-note/AN13732.pdf Application Note N 645036621402383989 2023-08-04 pdf N en Aug 3, 2023 645036621402383989 Application Note Y N AN13732: PCA9482UK 6 A 2:1, 1:2, and 1:1 Mode Switched Capacitor Direct Charger Application Note false 0 PCA9482 downloads zh-Hans true 1 Y PSP Y Y 应用笔记 1 /docs/en/application-note/AN13732.pdf 2023-08-04 1691155967957710813422 PSP 2 Aug 3, 2023 Application Note Many mobile phones have adopted features requiring high system performance, such as 5G, multiple cameras, and high resolution LCDs with multi-processors, increasing the demand for higher battery capacity.
