Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

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 ...

Portable battery-operated electronic equipment is becoming packed with more features requiring larger amounts of power, leading to decreased operating times between battery charges. Innovations such ...

STMicroelectronics’ L4985A/B and L4986A/B power-factor correction (PFC) boost converters look to simplify design and enhance flexibility by integrating 800V startup circuitry and additional valuable ...

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple ...

L4985A/B and L4986A/B power-factor correction (PFC) boost converters from ST integrate 800V startup circuitry and additional valuable proprietary features. The built-in high-voltage startup capability ...

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 ...
