Abstract: In some examples, a circuit includes sensing circuitry, a synchronization circuit, and a controller. The sensing circuitry is configured to provide a comparison result based on a comparison between a reference voltage and a feedback voltage. The synchronization circuit is configured to synchronize the comparison result into a clock domain to form a synchronous comparison result. The controller is configured to receive the synchronous comparison result, determine a predicted gate control signal based on the synchronous comparison result, determine a gate control signal based on the synchronous comparison result, provide the predicted gate control signal to the sensing circuitry as the feedback voltage, and provide the gate control signal for controlling a power converter.

Abstract: In an example, a system includes an SRAM configured to store a plurality of access control rules, where each rule is stored in a separate row. The SRAM is configured to store a plurality of context entries, where each context entry is stored in a separate row. The system includes a controller configured to receive a request for an access control rule for a memory location from a first context. The controller is configured to search one or more access control rules for the first context, where access control rules for the first context are stored in a binary tree format. The controller is configured to, responsive to finding the access control rule for the memory location, return the access control rule to the first context. The controller is configured to, responsive to not finding the access control rule, return a null notification to the first context.

Abstract: In an example, a voltage converter includes a pulse generator. The voltage converter also includes a high-side transistor having a gate coupled to the pulse generator, a source coupled to a first voltage terminal, and a drain coupled to an output node. The voltage converter includes a low-side transistor having a gate coupled to the pulse generator, a source coupled to a second voltage terminal, and a drain coupled to the output node. The voltage converter includes a charge lookup table coupled to the pulse generator, where the charge lookup table is configured to provide a charge duration. The voltage converter includes a discharge lookup table coupled to the pulse generator, where the discharge lookup table is configured to provide a discharge duration. The voltage converter also includes a latch coupled to the charge lookup table, where the latch is configured to store an indication of a supply voltage.

Abstract: In an example, a device includes a controller and a direct current (DC)-to-DC converter coupled to the controller and configured to provide a load current to a load. The device also includes a low-dropout (LDO) regulator coupled to the DC-to-DC converter. The controller includes digital logic, and the digital logic is configured to determine the load current. The digital logic is configured to turn on the LDO regulator if the load current is above a predetermined threshold. The digital logic is also configured to turn off the LDO regulator if the load current is below the predetermined threshold.

Abstract: This disclosure relates to a system that includes a centralized trim controller and a non-volatile memory that includes a trim sector configured for hosting trim data for one or more peripherals. The trim controller is configured to receive, for each of the one or more peripherals, trim values of the one or more peripherals from the trim sector of the nonvolatile memory, and provide the trim values to the one or more peripherals. Some trim values are updateable by receiving a password at the trim controller. If the password is valid, a timeout counter is initiated, during which time the trim value is updateable.
