Will current mode give way to voltage mode as digital power supply control becomes mainstream? Quite possibly – the arguments for voltage mode are more compelling. Doubtful? Let's take a closer look.

Digital control of switch-mode power supplies (SMPSs) is becoming practical thanks to the evolution of low-cost, high-performance devices with peripherals designed for power-conversion applications.

Modern buck switching-regulator circuits need to provide lower and lower output voltages to power leading-edge digital logic ICs such as digital signal processors ...

Average current-mode control, as shown in Figure 1, is common in continuous-conduction-mode (CCM) power factor correction (PFC). It has two loops: a voltage loop that works as an outer loop and a ...
