On April 8, 2025, Dalian University Holdings, a leading international semiconductor component distributor dedicated to the Asia Pacific market, announced that its subsidiary Pinjia has launched a new product based on Infineon IDP2308 controller and CoolGaN? A 200W ultra-thin wall mounted TV power supply solution for the 650V G5 transistor series.

With the increasing maturity of LCD screen technology and the continuous changes in consumer aesthetics, ultra-thin TV has become the new favorite of many families due to its simple appearance design and excellent space utilization. According to the survey, the mainstream ultra-thin TV thickness in the market is only 20mm. In this situation, the market also demands thinner and more efficient TV power supplies. To meet consumers' high expectations for ultra-thin TVs in terms of picture quality, sound effects, and intelligent operation, Da Da Da Da Pin Jia is based on Infineon IDP2308 controller and CoolGaN? The 650V G5 transistor series has launched a 200W ultra-thin wall mounted TV power supply solution, which can ensure that the TV maintains an ultra-thin appearance while having excellent performance and a long service life.

IDP2308 is a multi-mode PFC+LLC combination controller that integrates floating high-end drivers and startup units. It adopts a compact low pin count DSO-14 package, greatly reducing the demand for external components. And the built-in high-voltage starting unit of the controller, combined with advanced burst mode function, effectively reduces standby power consumption. Meanwhile, IDP2308 also supports burst mode control of synchronous PFC and LLC, and its configurable PFC driver can adapt to multiple operating modes, achieving higher efficiency and power density than traditional LLC plus MOSFET combinations. In addition, IDP2308 integrates configurable protection functions, further reducing the number of peripheral components. Its built-in processor supports communication with dpVision software through a half duplex UART interface, allowing users to easily program and configure PFC and LLC parameters, and store these settings in disposable programming memory.

CoolGaN?  The 650V G5 is a new series of high-voltage discrete devices launched by 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 its output capacitor (Eoss) and a 60% reduction in drain source charge (Qoss) and gate charge (Qg). These improvements enable the transistor to exhibit excellent efficiency in both hard and soft switching applications. Meanwhile, compared to traditional semiconductor technology, CoolGaN?  The power loss of the 650V G5 transistor is significantly reduced, and can be reduced by 20% to 60% depending on specific usage conditions. Thanks to these advantages, the product is able to operate at extremely low power consumption at high frequencies and has excellent power density.

With the help of these excellent components, this solution can be directly embedded inside the TV, effectively reducing the overall size of the TV and making the product more concise and beautiful. In addition to supporting TV power supply, this solution can also be widely applied to all-in-one computers and high-end LED power supplies, helping to create thinner, more efficient terminal products.
