The Design of an Intrinsically Safe Power Supply Based on LT4363 |
| |
| Abstract: | An intrinsically safe power supply is designed based on a high voltage surge stopper. The DC/DC power module LM2676T is used as voltage regulator module, and the surge stopper LT4363 as over-current and overvoltage detection device. The control circuit has double over-current and overvoltage protection circuit. The rated output of the intrinsically safe power supply is DC 12V/1A. The intrinsically safe power supply has many advantages such as small size, light weight, easy to install, stable output, high speed responding and so on. The feasibility of the design is verified by the electronic circuit simulation software LTspice. |
