| Abstract: | According to the application of low power loss single chip microcontrollers in oilfield truckmounted instrument, a power circuit is designed. The circuit is composed of a DC step down circuit based on MAX638 unit and an anti jamming circuit based on TL7705AC unit The circuit is characterized by small volume, low power loss and highly anti jamming It can be used in a low power loss system similar to 89C51/2 single chip unit |
