TOP204YN, from Power Integrations Inc. is an extensively used power management integrated circuit (PMIC) for a variety of electronic circuits. The device is commonly used for both ac-dc and offline switching applications, providing a critical link between the circuit’s input and its output. This article will provide an overview of TOP204YN’s application field and its working principle.
Application Field
TOP204YN has a wide range of applications in ac-dc and offline switching. It can be used in power converters, power switches, motor controls, telecom devices and industrial products. The device is particularly suited for use in hetl and commutation applications, as well as offline power switch designs that require substantial input protection and current limit. The device will operate over a wide input voltage range, up to 150V. It has been designed to maximize efficiency and minimize EMI (electromagnetic interference) emissions. It is suitable for applications in dangerous environments, since it has a lightning protection circuit included.
Working Principle
The TOP204YN is a highly integrated device composed of a power switching IC and two control ICs. The power switching IC is responsible for controlling the output voltage and current. It implements the hysteresis control switching controller with short-circuit, over-voltage and under-voltage protection. The power switch is based on an insulated-gate bipolar transistor (IGBT). The two control ICs are responsible for the PWM signal and over-current protection.
The main components of the device are the primary and secondary gate drivers, IC1 and IC2. IC1 is mainly responsible for generating the switching waveforms and, vice versa, IC2 is responsible for monitoring the current flow of the switching waveform. The protected current and voltage levels can be set via an external resistor divider, while PWM waveform frequency and duty cycle can also be adjusted using external resistors.
Conclusion
The TOP204YN from Power Integrations Inc. is a PMIC designed for use in a variety of ac-dc and offline switching applications. The device integrates two control ICs for the efficient and reliable control of the output voltage and current, and includes a lightning protection circuit for applications in dangerous environments. The device is highly integrated, efficient, and reliable, making it ideal for a variety of switching applications.
