Simple PS voltage splitters based on audio amplifiers

Sometimes it is necessary to split a single power supply in two or more parts which are not necessarily equal. This is the case with 6-, 12-, 15-, 24-, 36- or 48-V power supplies from dry batteries or ...

Test Setup Checks Transistors’ hFEs When Tight Control Is Important

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...

Test Saturation Voltage to Achieve High Efficiency

Efficiency is the name of the game in the design of power supplies. This is a major reason why switch-mode power supplies (SMPSs) are chosen for power-supply designs. However, even SMPSs have their ...

Simple PS voltage splitters based on audio amplifiers (Part 3)

From the point of view of the power supply the audio amplifiers are generally of two types. The first type is used mainly in applications with a single power supply. Some can be used with a dual power ...
