Abstract: In some examples, a device includes an amplifier circuit configured to receive a reference voltage signal at a first input, receive a feedback signal at a second input, and generate an output signal based on the reference voltage signal and the feedback signal. In some examples, the device also includes a feedback circuit including a soft-shaper circuit that is electrically connected to the second input of the amplifier circuit. In some examples, the feedback circuit is configured to sense a voltage step in the reference voltage signal, generate a voltage step across the soft-shaper circuit approximately equal to the voltage step in the reference voltage signal in response to sensing the voltage step in the reference voltage signal, and ramp a voltage level across the soft-shaper circuit to zero after generating the voltage step across the soft-shaper circuit.

Abstract: A switching mode power supply that supplies power to a load. The circuitry of the power supply of this disclosure may be configured to operate with a constant switching frequency over a range of input voltages and a range of load power demand. The circuitry of this disclosure may modulate a minimum on-time (Ton-min) for a duty cycle for an operating frequency of the circuit based on the magnitude of the input voltage. The circuitry may also operate in continuous conduction mode (CCM) or in discontinuous conduction mode (DCM) based on an operating region. The operating region is based on a combination of the demand from the load (Iout) and the input voltage (Vin). The circuitry of this disclosure may enter an operating region based on a first combination but exit the operating region under a second and different combination of Iout and Vin.

Abstract: The disclosure describes examples of integrate circuit (IC) chips. An IC chip includes a first detector configured to generate information indicative of whether an input supply voltage or power is greater than or equal to a first threshold, a second detector configured to receive a circuit voltage or current level and generate information used to indicate a status of the IC chip based on the received circuit voltage or current level, and a controller configured to cause the IC chip to enter a safe mode in response to both the first detector indicating that the input supply voltage or power is greater than the first threshold and the circuit voltage or current level being greater than a second threshold.

Abstract: Example current tracking circuits and systems as well as methods for tracking current are described herein. In one example, a current tracking circuit comprises a current mirror that receives a power supply input and a control signal as inputs, wherein the current mirror has a mirror ratio. The current tracking circuit also comprises a programmability sub-circuit coupled to the current mirror that trims a value of the mirror ratio. In another example, a method comprises performing current mirroring using a current mirror comprising a sense device, wherein a mirror ratio of the current mirror is based on a programmable sub-circuit. The method further comprises maintaining, by a voltage regulation loop, a collector potential of the sense device within a threshold difference level of a collector potential of a power device coupled to the sense device, wherein the sense device mirrors a current flowing in the power device.
