Abstract

An electronic controller with automatic adjustment to unknown input and load voltages is provided. Methods, devices, techniques and circuits for current control of buck converters are disclosed. In one example, a device is configured to receive a selected average current value for a current driver. The device is also configured to determine a parameter set for the current driver. The device is also configured to generate an output to the current driver such that the current driver outputs a switching signal having an average current corresponding to the selected average current value.

Description

technical field [0001] The present disclosure relates to electrical power converters, and in particular to electronic controls for electrical power converters. Background technique [0002] Electrical power converters are used to meet the specific current and voltage requirements of loads with available source power. For example, a chain of light emitting diodes (LEDs) may require a certain DC voltage and current to function properly. A chain of LEDs may typically be powered with a two-stage control device comprising an AC-DC voltage converter and a DC-DC current converter, typically a buck converter with an output voltage lower than the input voltage. [0003] LED chain controllers can be analog or digital. An analog controller makes lighting proportional to current, which has the advantage of simplicity and fast response time. However, the response of illumination to current is non-linear, and the spectrum of illumination also varies with current, causing the color of l...
