The LM3017EVM 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.
● Boost topology
● 8V to 12V input voltage range
● 15V output voltage (default setting)
● Up to 1000mA output current
● 600KHz fixed switching frequency
● Low shutdown current of less than 1µA
● True shutdown for short circuit protection
● Input side current limit
● Peak current mode control mode
● Simple slope compensation
●This device has limited built in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
