Abstract: The present subject matter facilitates chaining of multiple serial peripheral interface (SPI) compliant devices without requiring a bulky clock tree. Generally, in a serial clock distribution scheme as described herein, a fixed pulse based output cock (SCLK_OUT) is synchronized with the data output (SDO) from a respective device in the chain. The SCLK_OUT signal is connected to the SPI clock input (SCLK) of the following downstream device, and SDO is connected to the data input (SDI) of the respective downstream device. This allows the SCLK from the SPI master device to propagate through a theoretically unlimited count of devices in series. The master can resynchronize the MISO data from the SDO of the last part in the chain with the SCLK_OUT signal of the last device in the chain.

Abstract: A power converter circuit can be operated in a constant-current mode when a monitored output current exceeds a specified over-current threshold. A value representing an output voltage of the power converter circuit can be compared to a soft-start voltage reference value. The soft-start voltage reference value can be set (or reset) to a value representing the output voltage of the power converter when the difference between the soft-start voltage reference value and the value representing the output voltage of the power converter is greater than a specified threshold. The output voltage of the power converter can be regulated using the soft-start voltage reference value as a target voltage including ramping the soft-start voltage reference value at specified rate to maintain the soft-start voltage reference value within a specified range of a specified regulated output voltage value, such as to constrain a slew rate of the regulated output voltage.

Abstract: A control circuit eliminates the Zeno phenomenon in a power supply controller while transferring control from a primary side controller to a secondary side controller. The primary side controller generates a feedback voltage (e.g., threshold voltage) that is input to a comparator. An output node voltage of the control circuit is fed back to the linear amplifier to be compared with the threshold voltage. While the output node voltage is less than the threshold voltage, a charge pump is coupled to the output node of the control circuit. After the output node voltage has toggled around the threshold voltage a number of times, the comparator output node is coupled to the output node of the control circuit and the charge pump is decoupled from the output node. When the output node voltage has discharged to be equal to the threshold voltage, control is handed off from the primary side controller to the secondary side controller.
