Power Management ICs (PMICs) is an important device for the increasing scale of energy saving and environmental protection in the equipment. As a reliable and efficient energy saving device, PMICs can provide electric energy storage and conversion solutions for different end applications. The TOP222GN is a special PMIC under the PMIC family. This device belongs to AC/DC converters, offline switchers and is widely used in many applications.
The TOP222GN is an offline switcher IC intended for 20 watt applications. It includes a high voltage regulator with a quiescent current of only 600uA and comes with multiple features to improve its performance. The device features over-voltage, over-current, open-loop and thermal protection. It also features auto-restart, cycle-by-cycle current limit and programmable hysteretic peak current source. The device also has the ability to start-up on line if its input voltage is above its internal UVLO threshold.
The TOP222GN can work in either continuous or discontinuous conduction mode depending on the needs of the end application. The device\'s over-current, thermal and open-loop protections can be tailored to meet the specific system requirements. In addition, this IC also includes a 100msec single pulse limited transformer reset which helps prevent the transformer saturation issue. This makes the TOP222GN an ideal choice for automatic standby and standby applications.
The TOP222GN works on the principle of AC-DC converters. This device is designed to convert alternating current (AC) from a source such as mains power into direct current (DC). The TOP222GN uses a half-bridge topology, which contains two switching devices, such as MOSFETs, connected back-to-back and two capacitors, to create a DC output from an AC input. The device also contains a current-mode control circuit that regulates power output, enabling the device to operate at a specified frequency as it steps down the AC input to DC.
The TOP222GN is typically used in low-power offline switching applications, and is ideally suited for powering LCD TVs, AC adapters, set-top boxes, power supplies, and medical equipment. The device is particularly suitable for industrial control applications such as meters, smart home appliances and computers, where the performance and safety of the power supply must be guaranteed.
The ability to implement over-voltage, over-current, open-loop, auto-restart and thermal protection makes it a reliable and cost-effective solution. In addition, the device also has the ability to start up on line if its input voltage is above its internal UVLO threshold. With a quiescent current of only 600uA, the TOP222GN is an energy efficient device that enables the development of energy saving applications.
In conclusion, the TOP222GN device is an efficient and reliable AC-DC converter designed specifically for 20W applications. Its various features, such as over-voltage, over-current, open-loop, and thermal protection, make it a good choice for low-power offline power applications. It is a cost-effective solution for industrial control applications, smarter home appliances, computers, LCD TVs and medical equipment.
