TEXAS INSTRUMENTS  UCD3138LLCEVM-028  评估模块, UCD3138LLCEVM-028

The evaluation module helps to evaluate the UCD3138 64pin digital control device in an off line power converter application and then to aid in its design. The EVM is a standalone LLC resonant halfbridge DC to DC power converter. The EVM is used together with its control card, UCD3138CC64EVM-030, also an EVM on which is placed UCD3138RGC. The UCD3138LLCEVM-028 together with UCD3138CC64EVM-030 can be used as they are delivered without additional work, from either hardware or firmware, to evaluate an LLC resonant half bridge DC to DC converter.
