Abstract:
1. A switching regulator, comprising: a PWM controller configured to receive a PWM clock signal and generate a PWM control signal based on the PWM clock signal; a power converter configured to receive the PWM control signal from the PWM controller and provide regulated power to a load, the regulated power controllable by varying a duty cycle of the PWM control signal; a load transient detection circuit configured to detect an increase in load exceeding a detection threshold and assert a load transient detection signal responsive to detecting the increase in load exceeding the detection threshold; and clock reset logic to assert a clock reset signal responsive to the load transient detection signal being asserted; and a clock divider coupled to the clock reset logic, the clock divider to receive a fast clock signal and divide a frequency of the fast clock signal to generate the PWM clock signal, the PWM clock signal having a lower frequency than the fast clock signal, wherein responsive to the clock reset signal being asserted, the clock divider resets the PWM clock signal to synchronize a next clock cycle of the PWM clock signal with a next clock cycle of the fast clock signal occurring after the clock reset signal is asserted, and wherein the clock divider is further configured to continue to generate new clock cycles of the PWM clock signal at the PWM clock frequency after resetting the PWM clock signal.
