Designers of chargers and adapters delivering less than 4W will be able to eliminate the bulky, power-hungry linear transformer commonly found in these units with the LNK520 power-converter chip. The ...

Gas switches and linear transformer drivers (LTDs) form the cornerstone of modern pulsed power systems. Gas switches, typically relying on the ionisation of gas to establish rapid conductive channels, ...

• LVDTs produce a linear electrical output directly proportional to the position of a movable ferrous core of nickel-iron alloy. • Two secondary windings in the LVDT produce identical output voltages ...

Despite the emergence of cost-effective alternatives, many OEMs have persisted in using line-frequency transformers (linears) in low-power battery chargers and ac adapters. This is largely due to ...

In these conditions, surface temperatures of the primary and secondary windings as well as that of the PPTC device remain lower than the device protected by a thermal fuse (see Fig. 2). Data comparing ...

A primary-based CC/CV design slashes parts count to achieve cost parity with 3- to 4-W linear power supplies. Over the past few decades, switching power supplies have become an increasingly popular ...
