Abstract: In described examples, a controller includes a converter. The converter generates a first signal responsive to an input signal. A summing block is coupled to the converter. The summing block receives the first signal and generates a second signal. A limiter is coupled to the summing block and generates a third signal responsive to the second signal and a code signal. A logic block generates a target signal responsive to the third signal. The third signal transitions to an intermediate level at a first slew rate and the third signal transitions from the intermediate level to the target signal at a second slew rate.

Abstract: A controller includes: a pulse-width modulation (PWM) circuit; a control loop; and a reference voltage controller. The control loop has: a feedback input adapted to be coupled to an output voltage of a power stage; a control loop output coupled to a PWM control input; and an operational amplifier with a first feedback input, a first reference input, and an amplifier output, the first feedback input connected to the feedback input, and the amplifier output coupled to the PWM control input. The reference voltage controller has a reference voltage output coupled to the first reference input, the reference voltage controller configured to adjust a reference voltage provided to the reference voltage output responsive to a dynamic error estimate based on error in the operational amplifier.

Abstract: In described examples, a voltage regulator includes a processor. A register bank is coupled to the processor. A logic block is coupled to the processor and to the register bank. The logic block receives frames. The processor programs the logic block and the register bank based on at least one of the frames.
