Hi,
I am currently using the LM3880 for power sequencing the gate and drain bias of a pHEMT amplifier. From what I read in the datasheet the EN pin will enable the chip if it is tied to GND, and will disable the chip when the pin is floating. Is this correct? The screenshot below shows part of an schematic of one of the TI Reference Designs provided (https://www.ti.com/tool/TIDA-01416) so I believe that configuration would not involve any problem for powering up and down the system just by adding/removing the jumper on J12. Am I right?
Many thanks in advance.
Regards,
Pascual
