Hello,
I am using the LM2621 to boost 2.4V to 5V. I would like to use a MPU running at 2.4V to control the EN pin of the LM2621... but the MPU cannot provide the 0.7*VDD required to turn the device on. I can think of several ways to resolve this issue (all basically involving some sort of MPU-controlled switch between EN and VDD), but is there a recommended method?
Many thanks!
