I have a circuit using a TOP226 that works well. I need to be able to shut it off with a logic signal. I know you have JX and HX series that have shutoff function, but I'd like to stay with the TOP226 if it's practical, as we have inventory and the PCB is largely working.
Pls see the attached; can i use the DC line to drive the Control pin as shown in blue? How low a current can i get by with for the control current? (There's a lot more to our circuit than shown here, but i've included the power portion)
If i must change to the HX or JX, please give me an idea of the difference in the two series; without rigorous analysis, they look identical.
This is somewhat urgent as i discovered this need late in the design. I'd appreciate any help you can offer.
