Controlled voltage source for LED drivers
Abstract:
The present invention relates to an electronic device for driving a light emitting semiconductor device, which includes controlling means (CNTL) being adapted for controlling a switch mode power supply for supplying the light emitting semiconductor device in response to a sensing value received by the controlling means which is indicative of a voltage across a current source for determining a current through the light emitting semiconductor device, wherein the switch-mode power supply is controlled such that the voltage across the current source is minimum.
Abstract(Chinese):

本发明涉及一种用于驱动发光半导体器件的电子设备，其包括控制装置（CNTL），该控制装置（CNTL）用于响应于由控制装置接收的感测值来控制用于提供发光半导体器件的开关模式电源 其指示用于确定通过发光半导体器件的电流的电流源上的电压，其中控制开关模式电源，使得电流源两端的电压最小。
