TEXAS INSTRUMENTS LM3017EVM. 评估模块, LM3017 升压稳压控制器
The evaluation module EVM provides the design engineer with a fully functional asynchronous boost converter to evaluate LM3017 boost controller IC. The LM3017 is a versatile low side NFET controller incorporating true shutdown and input side current limiting. It is designed for simple implementation of boost conversions in Thunderbolt technology. The LM3017 can also be configured for flyback or SEPIC designs. The input voltage range of 5V to 18V accommodates a two or three cell lithium ion battery or a 12V rail. The enable pin accepts a single input to drive three different modes of operation, boost, pass through or shutdown mode. It provides an adjustable output in order to drive the power load switch or mux for the host Thunderbolt.
