This article describes the Battery Backup Regulator (LT1020). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: LT1020.

A low-loss way to implement a”glitch-free” battery backup for a memory or similar circuit is shown on the following schematic diagram. To make LT1020 does not conduct under line-powered conditions, we have to arrange the feedback string. The line LT1020 begins to go off when the lie goes down, which allows the battery-driven LT1020 to turn on and maintain the load.
