The charger and adapter
The charger/adapter
Power Integrations can provide a series of highly integrated, high voltage IC and independent controller for mobile phones, digital camera, cordless phone, network equipment, and other applications of an off-line switching Power charger/adapter.Each IC includes a high-voltage power MOSFET, it used in a single chip control and protection circuit, and InnoSwitch product series also has the synchronous rectifier drives.The BJT control IC adopts the most advanced BJT drive systems and emitter switch/the base drive, to ensure to provide high efficiency and high reliability.Its features include can improve the reliability of the electric current to flow limit and with automatic failover thermal shutoff protection, and can reduce EMI frequency jitter.
The laptop adapter application
Power Integrations provides a series of for laptop adapter Power supply application integration an off-line Power conversion with high voltage IC.In laptop adapter applications use the TOPSwitch - JX series largest device, can design compact and efficient laptop power supply, and under the environment temperature as high as 40 ° C in an airtight shell in safe operation.
TOPSwitch - JX also provide slim encapsulation (eDIP encapsulation), use it to design the output power for 20 to 100 W thin, compact, portable power supply.
Each IC device used in a single a high power converter and PWM controller with rich characteristics.Its features include current current limit, improve reliability and thermal shutoff protection with automatic failover properties features, to reduce the electromagnetic interference of frequency modulation characteristics and significantly reduces the standby power consumption EcoSmart ® technology.
PowiGaN
PowiGaNIs Power Integrations on its own research and development of gallium nitride (GaN) technology.In PI highly integrated off-line flyback switch IC, traditional PowiGaN switch instead of primary side silicon transistors, so as to reduce the switching loss, compared with those of silicon devices PowiGaN product can achieve a smaller, lighter weight, higher efficiency of the chargers, adapters, and open the power supply.IC based on PowiGaN throughout the load range of efficiency is as high as 95%, in enclosed adapter does not need to heat sink is as high as 100 w power output can be realized.
