In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

1. Converter circuit is 157 mm3 including two chip inductors. The basic series capacitor buck converter shown in Fig. 4 harnesses the hybrid switched capacitor/inductor approach. It uniquely combines ...

Today’s electronic systems are becoming more and more complex, with an increasing number of power rails and supplies. To achieve optimum power solution density, reliability and cost, often system ...
