Abstract: A Red, Green, Blue Light Emitting Device (RGB LED) backlight color control system includes an RGB LED backlight comprising a red LED, a green LED, and a blue LED. A driving current regulator is coupled to each of the red LED, the green LED, and the blue LED. A backlight power control is coupled to each of the driving current regulators and operable to receive adjustment data and use the adjustment data to adjust the driving current supplied by at least one of the driving current regulators to at least one of the red LED, the green LED, and the blue LED. By adjusting the driving current supplied to the red LED, green LED, and/or the blue LED, color pallet points on a color triangle (associated with a display that uses the RGB LED backlight) are shifted to achieve the color desired by the user, avoiding the loss of color pallet points in the color triangle that occurs with conventional re-mapping techniques.

Abstract: Sensing current flowing through a semiconductor device includes providing an input pin to receive an input, providing an output pin coupled to a predefined voltage source, providing a control pin to receive a control signal for controlling a flow of current between the output pin and the input pin, and electrically coupling a Kelvin sense pin to an output pad located on a semiconductor die of the device. An electrical path from the output pad to the output pin has a predefined resistance. The current is Kelvin current sensed using the predefined resistance. A flow of an output current provided to a load coupled to the device is interrupted when a value of the current is greater than a predefined value.

Abstract: Regulating a direct current-to-direct current (DC-DC) converter, a semiconductor switch having an improved current sensing technique is used to switch a DC voltage input at a predefined frequency. The switch includes a control pin to receive a control signal for controlling a current flowing between an input pin and an output pin. The switch also includes a Kelvin sense pin electrically coupled to an output pad located on a semiconductor die of the device for sensing the current. An electrical path from the output pad to the output pin in the form of a conductive lead wire has a predefined resistance. The current is Kelvin current sensed using the predefined resistance to tightly control deviation in the current beyond a predefined range.
