.Introduction to TOP266KG Application Field and Working PrincipleThe TOP266KG is a highly efficient and capable offline switcher for PMIC AC/DC conversion and is ideal for LED TV applications. It provides a broad range of features that make it suitable for a variety of demanding applications. This article will provide an overview of the TOP266KG’s application field and working principle.Types of ApplicationsThe TOP266KG is suitable for a wide range of uses, and is especially suitable for applications in LED TV, digital video recorder (DVR), set-top box (STB), digital signage, and home entertainment. It is also suitable for medical and industrial applications.FeaturesThe TOP266KG has a variety of features that make it suitable for an extensive range of applications. These include:• Low start-up and dropout voltage, which increases efficiency and reduces thermal stress.• High power density, which allows for a compact design and simpler layout.• Broad operating temperature range, which ensures reliable operation even in challenging environments.• Primary side sensing feedback, which reduces components count and shortens loop delay time.• Synchronous rectification efficiency, which further increases efficiency.• Advanced protection features, which provide comprehensive protection from overloads and short circuits.• Active burst mode operation, which reduces no-load power consumption.Working PrincipleThe TOP266KG is a flyback switcher, which works by synchronously rectifying the ac input and then storing the energy in a primary inductor. The stored energy is then used to drive the main power switch, which in turn energizes the output. The system then operates in a continuous cycle.The TOP266KG includes proprietary features such as primary side sensing feedback and active burst mode operation. With primary side sensing feedback, the input voltage is sensed directly on the primary side without the need for optocouplers or other secondary sensing components. This reduces components count and improves efficiency and loop delay time.With active burst mode operation, the control IC turns off the main power switch when the output voltage is within 10% of the set value, resulting in a dramatic reduction of no-load power consumption. The switch is reactivated when the output voltage is outside the window and the cycle is repeated.ConclusionThe TOP266KG is a highly efficient and capable PMIC AC/DC converter and offline switcher. It is ideal for a wide range of applications, including LED TV, DVR, STB, digital signage, home entertainment, medical, and industrial. It features a number of features that make it suitable for a variety of applications, including low start-up voltage, high power density, broad operating temperature range, primary side sensing feedback, synchronous rectification efficiency, and advanced protection features. Its working principle is that of a flyback switcher, which works by synchronously rectifying the ac input and storing the energy in a primary inductor, and then using this energy to drive the main power switch. It is further enhanced by proprietary features such as primary side sensing feedback and active burst mode operation.
