Hello TI support,
can you please help me in this matter? I still have not solved this issue.
The stepup is used to boost 12Volt to 24 Volts. all works well. but when I connect the SD pin to 5 Volts, it will not shut down. what happens is that the output Voltages drops from 24 Volts to 11Volts. not lower or zero.
I use a 68k normally to gnd. I have put in series a 10k to plus 5Volt. when I connect this 78K to plus 5 Volt, it lowers to 11Volts.
when I connect the junction 10k-|-68k to the gnd, it delivers 24Volts again.
please respond.
kind regards,
Rob van VReden
