TOP264EG is a high performance, monolithic, off line switching regulator controller that incorporates the latest power MOSFET technologies. It consists of an efficient MOSFET switch, a high voltage oscillator, an error amplifier circuit, a current sensing circuit, a temperature sensing circuit and an over temperature protection circuit. TOP264EG is ideal for Low and medium power offline applications such as AC/DC converters, LED drivers, UPS systems or adapter systems.
Applications
TOP264EG can be used in a variety of applications and has a wide range of capabilities including:
- AC/DC Converters – used in switched mode power supplies, adapters and brick chargers, server power supplies, etc.
- Offline Switchers - used in LED lighting, telecom equipment, microprocessor DC-DC converters, motor control and scan converters.
- Voltage Regulators (UPS Systems) – used for AC-DC power transducers, AC-DC switching regulators, etc.
Working Principle
TOP264EG incorporates several circuits, each operating in harmony to provide exceptional performance and efficiency. When the power is first connected, the over temperature protection circuit begins to monitor the temperature of the device. Before the oscillator turns on, the current sensing circuit monitors the input current and the error amplifier sets a reference voltage for the switch to turn on. Once the current reaches the set level, the oscillator starts a PWM cycle that is constantly validated by the error amplifier. The MOSFET switch monitors the input voltage and switches on/off as per the PWM cycle, providing stable output voltage and current. When the input current exceeds the set level, the over temperature protection circuit turns off the switch until the temperature drops again.
TOP264EG is a reliable, efficient and cost effective solution for low and medium power off line applications. Its unique design makes it ideal for high power and high efficiency applications, allowing manufacturers to reduce device size, improve system performance and reduce overall cost.
