As portable systems rapidly evolve, however, the integrated PMIC cannot keep up with peripheral power requirements. Dedicated LDOs must be added in the later stages of system development to power such ...

Simply connecting a power supply to a load is not always so simple. Voltage drop due to wires, cables, connectors and circuit board traces can cause considerable regulation errors at the load. It is ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...

Sponsored by Texas Instruments: Meeting demands of 1% to 3% accuracy in supply designs for many applications, especially those in tough environments, can be rather challenging. A new dc-dc converter ...

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 ...
