Abstract: A system for serial communication may include a first device and a plurality of devices on a series connection. The first device may have a master circuit and the plurality devices may have a slave circuit. The master circuit may enable the first device to communicate with the plurality devices having the slave circuit on the series connection. The master circuit may enable the first device to send a command frame on the series connection. The command frame may include an execution mode command and a plurality of commands. The second devices may execute the commands within the command frame at or after the end of the command frame based on the execution mode command indicating a synchronous mode of command execution; and may execute the commands within the command frame at the ends of individual ones of the commands based on the execution mode command indicating a non-synchronous mode of command execution.

Abstract: A system that provides intelligent constant on-time control may include a first switch coupled to a power input; a second switch coupled to the first switch; a switching node between the first switch and the second switch, the switching node configured to be connected to an inductor and a power output; feedback paths coupled to (1) a synthesized node and (2) the power output, the feedback paths enabling feedback of signals from (1) the synthesized node, and (2) the power output; and a controller coupled to the feedback paths. The controller may be configured to control a voltage at the power output based on a combination of the signals carried by the feedback paths.
