Introduction
TOP225YN is a current-mode PWM-controlled AC/DC converter with integrated power management and protection functions. It is widely used in applications such as PC and home audio systems, monitor displays and white goods.
This article will provide an overview of the TOP225YN application field and working principle.
Application Field
TOP225YN offers several advantages when applied in AC-DC and DC-DC applications, such as the booming home audio market. Among the advantages are high peak currents, low standby power consumption and low EMI. When used in audio amplifiers, the chip is able to reach high peak currents for good sound quality.
TOP225YN is also widely used in instrumentation and industrial automation, with superior overload and overvoltage protection for great voltage control.
Working Principle
The working principle of TOP225YN is based on current-mode Pulse Width Modulation (PWM) control. This type of control allows for more precise voltage regulation and faster response to changing loads. The chip uses an external power factor correction (PFC) diode to improve efficiency and accuracy.
The main components of the TOP225YN are a high-side switch (HS) and an auxiliary rectifier, as well as several current-sense resistors. The HS and auxiliary rectifier switch on and off in the same cycle, while the current-sense resistors measure the current passing through the circuit and send a feedback signal to the chip.
TOP225YN also provides a number of features for better performance, such as current-mode PWM control, overload protection and soft start. These features help to maximize efficiency, reduce noise and ensure safety.
Conclusion
TOP225YN is a highly efficient AC/DC and DC/DC converter designed for applications such as audio systems, monitors and white goods. The chip is based on current-mode Pulse Width Modulation control and provides high peak currents, low standby power consumption and improved voltage regulation for better performance. Its features include overload protection, soft start and current-mode control for greater safety and accuracy.
