Here’s a low-cost circuit to convert 6V DC into 12V DC. It uses no transformer and is easy to construct with few components. The circuit is built around IC 555, which generates the required frequency of around 2 to 10 kHz to drive power transistor BD139 (T2). The output frequency of the IC can be …
