Auto infotainment products (multimedia and telematics) are demanding more power and challenging a vehicle’s power-management systems. This application note explains average-current-mode control (ACMC) ...

A proposed new model for current-mode control retains the strengths of existing models such as ease of use and the ability to capture subharmonic oscillations, while improving on weaknesses like dc ...

Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

The course is focused on current-mode control techniques, which are very frequently applied in practical realizations of switched-mode. Upon completion of the course, you will be able to understand, ...

Given: V = L di/dt I(t) = I(t0) + 1/L × ∫ V(t) dt Rearrange: (L/V) × (I(t) - I(t0)) = dt Using the formula: PWM on-time = (L/V) × 2 × (IDESIRED - ISTART) For most applications, the input voltage can't ...

A dc-to-dc converter regulates a varying input voltage to a (usually) fixed output voltage via a feedback control system. The feedback control system should be as stable as possible to avoid ...
