Lots of op-amp based circuits require dual (symmetrical) power supply. This tiny circuit is a simple solution which provides +/-12V DC 300mA from single 5AV DC input. The board is based on LM2588-ADJ IC from Texas instruments. Step up from 5V to dual 12V is the best part of the circuit since 5V is easily available.
The LM2588-adj regulator IC specifically designed for fly back, step-up (boost) and forward converter applications, this regulator are cost effective and simple to use due to minimum number of external components. The power switch is a 5A NPN device that can stand-off 65V. Protecting the power switch are current and thermal limiting circuits, and an adjustable frequency that can be programmed up to 200Khz. other feature include soft start mode to reduce in rush current during start up, and current mode control for improved rejection of input voltage and output load transient and cycle-by-cycle current limiting.
- Input 5V DC (4 to 6V DC Possible)
