Introduction
TOP234GN is a member of the Power Integrations TOPSwitch product family. It is a high performance, cost effective and versatile AC/DC PWM controller, which can provide excellent performance for a variety of offline switchers and AC/DC converters applications. With the ability to detect and limit secondary side peak inrush current and it offers very low standby power and reduced electromagnetic interference (EMI). It also has smart functions, such as Active Burst Mode™ operation and Power Factor Correction (PFC) performance across a wide input voltage and load range.
Application Field
TOP234GN is suitable for a wide range of applications including AC-DC converters, DC-DC converters, and offline switchers. Its wide range of features makes it a suitable device in many different applications including LED lighting, computers, consumer electronics, mobile device chargers, and other home appliances.
For AC-DC converter applications, TOP234GN’s user programmable active burst mode power saving technology is perfectly suited for small power supplies used with devices such as notebook computers, small AC adapters, and LCD digital set-top boxes. TOP234GN’s active burst mode operation reduces power consumption by up to 50% or more compared with conventional PFC solutions, making TOP234GN perfect for any AC/DC application where high power savings are desired.
TOP234GN also provides additional protection against inrush current and short circuit, which makes it suitable for high voltage DC/DC converters and offline switchers. TOP234GN can also provide power factor correction (PFC) functions to help reduce conducted EMI and static power consumption.
Working Principle
TOP234GN is a current mode PWM controller that features advanced cycle-by-cycle current limit, line feed-forward and Max Peak Current Limit (MPCL) technology. The MPCL limits the peak of both primary and secondary side current.
When operating in active burst mode, the controller switches to a low power standby mode when AC input is detected but there is no load. The controller monitors both the AC input voltage and the current draw at the output of the converter. When the current draw drops below the set point, the controller deactivates the load and switches to a low power standby mode. This enables the supply voltage and current to reduce, resulting in large energy savings.
The TOP234GN also incorporates several safety features, such as a short circuit protection, a soft start ramp, and road protection circuitry. The device also has a constant frequency OVP circuitry, which helps ensure that the output of the converter remains at a constant voltage level.
Conclusion
In summary, TOP234GN is a versatile AC/DC PWM controller with a wide range of applications, from AC-DC converters to DC-DC converters and offline switchers. Its advanced power saving features such as active burst mode and power factor correction performance help to reduce power consumption and conducted EMI, making it the perfect solution for wide range of applications.
