What are the voltage requirements for the BOOT pin on the LM2621? The data sheet gives no indication other than an operating range of 0 to 10 V. The WebBench seems to want it set at or above 5 volts. When you create a design where VOut = 5 V it connects Boot to VOut. However, I am trying to create a design with a 2.5 V input and 3.3 V output. In this case the WebBench adds an external 5 volt supply to connect boot to. Since I dont have a 5 volt supply available, this would be a problem. Any guidance on the requirement for the Boot pin
Thanks
