Volt regulators such as the LM708, and LM317 series (and others) sometimes need to provide a little bit more current then they actually can handle. If that is the case, this little circuit can help ...

This reference design presents an automotive VFD power-supply controller used as a boost circuit that will maintain a constant voltage in the event when the battery is affected by cold temperatures.

The power supply that's described here boosts the voltage from a 1.5-V flashlight cell to 3.5 V across an LED, while the LED and flashlight cell are in series with the power supply. What spawned this ...

This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V. Overcurrent damage of PFC front-end boost ...
