The two most common forms of control in dc/dc switching power converters are CM (current-mode) and VM (voltage-mode) control. Each method has its own advantages and disadvantages. CM control provides ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...

While current-mode control (CMC) remains the much preferred PWM scheme for switchmode power supplies, its advantages aren't automatic. Indeed, ensuring stability in a switchmode supply involves such ...

Transient response is a key performance parameter for the multiphase voltage regulator, especially in microprocessor applications. Conventional pulse-width modulation (PWM) schemes have delay times ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...
