Hello,
I am using the LM2670X-ADJ IC in a buck boost configuration successfully. The schematic is attached below for you. I need to be able to enable and disable this IC. How can I do this?
The datasheet excerpt is also given below. It shows that the ON/OFF pin can be set to 0.8V to 2V to turn the device ON. Likewise a voltage between GND and 0.8V will turn the device OFF.
Can you advise what voltages do I need to set the ON/OFF pin to enable or disable my Inverting Buck Boost? The current implementation has this pin floating (Pin 7). What levels can I apply to Pin 7 to enable and disable the part?
The section of the D/S is given below:
Many Thanks,
Jorge Vega
