Power Management Integrated Circuits (PMICs) are becoming increasingly important in many industrial applications. One type of PMIC is the AC/DC Converter, which is responsible for converting alternating current (AC) to direct current (DC). The L6566BHTR, a type of offline switcher, is widely used for AC/DC conversion applications. This article will explain the application field and working principle of the L6566BHTR.

The L6566BHTR is capable of providing a Constant Voltage (CV) output at a maximum input voltage of 400VAC. It is an ideal choice for various fixed-output standby power applications such as LED Driver Power Supplies and LED Backlight LED modules. The L6566BHTR is also suitable for dimming applications up to a power level of 30W, and it is designed to protect against short circuit, overvoltage and thermal overload conditions.

The application field of the L6566BHTR is varied, and it can be used in both residential and commercial settings. It is commonly used in powering lighting systems, charging smartphones, and in many other related applications. The L6566BHTR can be used as part of an overall power management system, as it provides an optimal solution for delivering a constant current and voltage output.

The working principle of the L6566BHTR is based on the Four Switch Resonant Converter (FSRC) topology. This topology allows for an efficient, flexible, low-cost, and low-noise operation. The design of the L6566BHTR combines a level-shift circuit and a half-bridge rectifier to provide a high-efficiency solution for AC/DC conversion. During operation, the outputs of the four-switch resonant converter provide a driving current to the rectifier, allowing for a efficient and reliable power conversion.

The main features of the L6566BHTR include a wide operating range, low output ripple, and fast transient response. The L6566BHTR is also designed to limit the output voltage and current, in order to protect the connected load from damage. In addition, the L6566BHTR utilizes a shutdown input pin, which allows the system to be shut down in case of over current or over temperature.

The L6566BHTR is a highly reliable offline switcher, and it is suitable for a wide variety of AC/DC conversion applications. It is an optimal choice for LED lighting and LED driver power supplies, and can be used as part of an overall power management system. The Four Switch Resonant Converter (FSRC) topology of the L6566BHTR provides an efficient, low-noise, and low-cost operation, making it a great choice for various applications.
