Adding charge pump and LDO components to a boost converter circuit creates a cost-effective power supply for LCDs and other portable applications. Many portable devices use LCD displays. These ...

Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

Combining the operation of a boost regulator and a negative voltage converter can generate a negative supply from a single low voltage supply. The circuit in Figure 5 shows a standard application ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

Diodes has introduced a boost converter that can supply constant voltage or constant current to drive backlights, with a dimming ratio of 100:1. Called AL3353, it has an input voltage of 9V to 40V – ...

We have a love/hate relationship with LiIon batteries. They pack all this power in such a small and light package. But for running 3.3 V devices, they’re cumbersome. They need to be stepped down a ...

If you are planning on creating some sort of Nixie tube display, you will undoubtedly need to find yourself a high voltage DC power supply. If you don’t want to add a transformer to your project, you ...
