I have a couple of Chinese programmable lab power supplies. Both switch mode power supply (SMPS) systems are rated for 110V-220V AC input. But the UNI-T UTP1306 power supply has an input voltage ...

The input-rectifier stage of anoffline power supply converts anac-line voltage to a dc voltage, whichpowers a dc/dc converter. If you configurethe rectifier section as a full-wavebridge for a ...

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

This file type includes high-resolution graphics and schematics when applicable. For applications such as motor control or power supplies, it’s often necessary to know whether the ac line is at 120 V ...

Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...

Power management of battery-powered electronic devices is becoming increasingly more important for the microelectronics industry. This white paper details the difference between low dropout (LDO) ...
