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 […]

This is 7.5V Uninterpretable Power Supply simple circuit. This circuit was used in many applications as a battery backup for low power requirements. This circuit contains a bridge rectifier, an electrolytic capacitor,  and a transformer followed by a Zener controlled series pass transistor. This circuit can generate +7.5V stable output. Here is the circuit: The stand-by battery, 7.5V, is connected […]

Basic interruptible Power Supply Circuit consist of regular power supply adapter and battery connection. This basic system is a “hot” battery connection, meaning that there is no switching mechanism in connecting and disconnecting the battery, the battery is always connected! This hot connection is very simple to implement and very robust because there would be no switching delay, the output […]
