A microcontroller requires dc operating power in the 2 to 5.5V range, an amount that a battery or a secondary power source can easily supply. However, in certain situations, a microcontroller-based ...

The new AC/DC linear regulator from Texas Instruments Inc. (TI) claims to offer 75% higher efficiency and two times the power density compared to other linear regulators. The TPS7A78, the latest ...

Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus. One difference compared to a dc-dc converter is that you can use a linear power supply with an ac ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
