On April 8, 2025, DDA Holdings, a leading international distributor of semiconductor components in the Asia Pacific market, announced the launch of Infineon's IDP2308 controller and CoolGaN? 650V G5 transistor series 200W ultra-thin wall-mounted TV power supply solution.

With the increasing maturity of LCD screen technology and the continuous change of consumer aesthetic, ultra-thin TV TV has become the new favorite of many families with its simple appearance design and excellent space utilization. According to the survey, the thickness of the mainstream ultra-thin TV in the market is only 20mm. In this case, the market also puts forward thinner and more efficient requirements for TV power supplies. In order to meet consumers' high expectations for ultra-thin TVS in terms of picture quality, sound effect and intelligent operation, the Infineon IDP2308 controller and CoolGaN? The 650V G5 transistor series introduces a 200W ultra-thin wall-mounted TV power supply solution that ensures excellent performance and long service life while maintaining the ultra-thin appearance of the TV.

The IDP2308 is a multi-mode PFC+LLC combination controller that integrates a floating high-end drive and boot unit. It features a compact, low-pin DSO-14 package that greatly reduces the need for external components. And the controller's built-in high voltage starting unit combined with advanced burst mode function, effectively reduce the standby power consumption. The IDP2308 also supports simultaneous PFC and LLC burst mode control, and its configurable PFC driver can adapt to a variety of operating modes to achieve higher efficiency and power density than a traditional LLC plus MOSFET combination. In addition, the IDP2308 integrates configurable protection functions to further streamline the number of peripheral components. Its built-in processor supports communication with dpVision software via a half-duplex UART interface, allowing users to easily program and configure PFC and LLC parameters and store these Settings in one-time programming memory.CoolGaN? The 650V G5 is a new family of high voltage discrete devices from Infineon. Compared to previous products, CoolGaN? The performance of the 650V G5 transistor has been further improved, with a 50% reduction in energy stored in the output capacitance (Eoss) and a 60% reduction in drain-source charge (Qoss) and gate charge (Qg), which enables the transistor to demonstrate superior efficiency in both hard and soft switching applications. At the same time, compared to traditional semiconductor technology, CoolGaN? The power loss of the 650V G5 transistor is greatly reduced, which can be reduced by 20% to 60% depending on the specific use. Thanks to these advantages, the product is able to operate at high frequencies with very low power consumption, with excellent power density.

With these excellent devices, the solution can be directly embedded inside the TV, effectively reducing the size of the TV machine, making the product more concise and beautiful. In addition to supporting TV power supply, this solution can also be widely used in computer all-in-one and high-end LED power supply, helping to create a more thin and efficient end product.Core technical advantages:
