Abstract:
A switch mode power supply (voltage converter) is adapted as a current-mode control buck regulator for different loading conditions. The voltage converter operates in a continuous conduction mode (CCM) during heavy load conditions using pulse width modulation (PWM). When a zero-current detector determines no inductor current during light load conditions (discontinuous conduction mode (DCM) region), the controller initiates adaptive duty control using pulse frequency modulation (PFM). Adaptive duty estimation circuitry provides controllable energy to charge the power inductor to maintain voltage accuracy and maximize efficiency when in the PFM mode. Using clock synchronization and a single control-loop, smooth transition between PFM, PWM, and bypass modes is automatically performed. Clock synchronization from a master oscillator provides a base for frequency division in different operation modes which gives controllable evenly distributed switching harmonics. An inductor zero-current detector triggers an adaptive estimated duty cycle that is synchronized with the master oscillator.
