Hi Spec, The reason why I started to look at the gate driver optos is as follows I am looking to drive some commercial ( Meanwell ) switchmode powersupplies in a series/parallel combination under a controlled regime. They require a variable voltage to control the output. I had seen these opto drivers in the past but could not recall details. Unfortunately they are a bit unsuitable ( too low a drive ). |

--- Quote ---Toshiba TLP series. Usually more expensive, but with better driving capability. Or if you have access to cheap P-JFETs for the turn-off circuit, go with VO1263. --- End quote --- Thanks, Do we have Chinese manufacture of such devices? also I wonder what would be the turn on time of these devices with two 20N60 MOSFETs acting as a an SSR, what sort of times should I expect? Also there are lot's of cheaply P-JFETs out there ;) |

Maybe we could help with an alternative approach. |
