About USB Charging Power Adapter
The latest USB charging power adapter manufacturer solution
 
Although the new battery life technology is constantly updated, it is reported that the charge-free technology has been developed, but the current general population still needs to charge with a USB charging power adapter, and the highly integrated USB charging power adapter solution improves portability. The solution uses RT7786+RT7207 as the main chip, which can realize low-cost, small size and light weight product design at the same time.
The miniaturized adapters represented by the USB power adapters of Apple's mobile phones are becoming more and more popular. More and more SMD miniaturized packaging of circuit components can make the conventional power chargers more compact. It combines beauty and portability.
The RT7786+RT7207 is a highly integrated PWM + USB-PD Controller with many features to enhance the performance of low-power Low-power Flyback transformers, especially for USB charging applications. Association certification. The solution can be completed with the most simplified circuit design. Using the RT7786+RT7207 will enable low cost, small size and light weight product design.
To reduce standby power consumption, the solution uses a proprietary Green-Mode design mode that is linearly down-converted below the Light-Load state. Using proprietary Green-Mode design products will easily comply with power supply regulations. The RT7207 is a highly integrated IC with built-in CC/CV, LDO, TL431, OVP, OTP, SR, Cable Comp, Charge Pump, PMOS drive, Quick Discharge, Single Fault, PWM Off @ OVP, and no additional Increase the line.
