In today's market of electronic products everywhere, USB power adapter 5V 3A has become a home essential goods, power adapter manufacturers in the choice of the power adapter chip will directly affect the overall quality of the power adapter to a certain extent, so for enterprises to choose a appropriate power adapter chip suppliers is critical, Li Microelectronics recommended adapter 5v3a high-performance chip solution.
Energy efficiency 15W adapter six applications (AP8266 SOT23-6)
■ Input voltage: 90 ~ 264Vac full voltage range;
■ output specifications: ± 0.25V. 5 /. 3A
■ Output Power: ≤15W
■ IEC60950 designed to meet relevant safety requirements;
■ has a recoverable short-circuit protection, output overload protection;
■ secondary feedback device after a fault, overload can enter, troubleshooting recovery;
■ full load maximum efficiency:% greater than 84 
AP8266 is a current mode PWM control of the highly integrated chips , built green operation mode is greatly reduced power standby mode, energy efficiency is easier to meet international standards, while AP8266 rich to improve the reliability of the protection function, comprising: a by-cycle overcurrent, overload, overvoltage clamp and overvoltage, undervoltage lockout, over-current protection has a line voltage comprising compensation, so that the full input voltage range can be obtained more accurate overload. 
5v3a adapter provides high-performance chips 12V3A output, full load efficiency greater than 84% lower than the standby power consumption of 150mW carrier, conducting a test to meet the requirements of EN5502 CE Mains ClassB, more adapter programs related to the high-performance chips 5v3a schematic, power input and output Chu Specifications, BOM table may apply to Li Microelectronics.
