The InnoSwitch-CP family of off-line CV/CC flyback switching ICs incorporate a constant power output profile which, when paired with an adaptive-voltage protocol such as Qualcomm Quick Charge 3.0 or USB-PD, permits smart mobile device makers to optimize charging time across a range of products. Developers employing adaptive charging technology achieve dramatically faster charge times, improved charging efficiency and backward compatibility with the 5 V USB BC 1.2 specification, while minimizing overall thermal management and battery charging system cost.
The ICs use the company’sFluxLink technology that enables secondary-side control to be implemented with the simplicity and low component count usually associated with primary-side regulation. No-load consumption at 230 Vac is <10 mW, while full-load efficiency exceeds 90%. The INN2214K IC delivers 15-W output power for universal voltage chargers and adapters, while the larger INN2215K part delivers up to 22 W for similar applications.
