A system may include a processing engine and an analog-to-digital conversion interface subsystem communicatively coupled to the processing engine. The processing engine may be configured to process feedback data converted from analog feedback data to digital feedback data, wherein the feedback data includes a plurality of data stream sequences converted from the analog feedback data to the digital feedback data at a sample rate and based on processing of the feedback data, generate digital control signals for controlling a system under control. The analog-to-digital conversion interface subsystem may be configured to flexibly control the processing of the processing engine and the generation of digital control signals by the processing engine to minimize latency in the generation of the digital control signals due to processing of the processing engine.

Flexible latency-minimized delivery and management of disparate-rate data streams and sub-streams for processing

A low voltage lamp includes a boost converter stage and a load. The load may include low voltage light producing elements including low voltage light emitting diodes. The boost converter stage receives an electronic transformer output and includes an inductor coupled to a switch and a switch controller that receives one or more controller inputs. Inductor current may be returned to the transformer when the switch is closed and provided to a rectifier coupled to the load when the switch is open. Controller inputs may include a transformer input that receives the transformer output, a sense input indicating switch current, and a load input indicating load voltage. Controller logic may synchronize assertions of a control signal for the switch with edge transitions of the transformer output to maintain peak inductor current within a specified range and to selectively transfer stored energy in the inductor to the load or back to the transformer.
