Tool/software:
Hi. I've used this part many times, always tying the enable pin (pin 13) to VIN. On a new application, I need to control it with a 3.3V signal (H= on, L = off). I saw that the minimum voltage V+EN(HI) for this pin is 2V, and despite feeding it 3.3V, it doesn't work. The description in the pinout table is not really very clear to me either. My VIN is 24V, and VOUT is 12V. Could you please help clarify if I can drive the EN pin directly from my 3.3V line, or if I need to add some transistor circuitry that my 3.3V line controls to feed VIN to the EN pin? Or if there's another way?
Many thanks
