Filed:
Mar 26, 2008
Appl. No.:
12/056237
Inventors:
Bin Zhao - Irvine CA, US
Jack W. Cornish - Foothill Ranch CA, US
Brian B. Horng - Irvine CA, US
Victor K. Lee - Irvine CA, US
Andrew M. Kameya - Irvine CA, US
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H05B 37/02
US Classification:
315299, 315185 S, 315308, 315312, 315360
Abstract:
Power management in a light emitting diode (LED) system having a plurality of LED strings is disclosed. A voltage source provides an output voltage to drive the LED strings. An LED driver monitors the tail voltages of the active LED strings to identify the minimum, or lowest, tail voltage and adjusts the output voltage of the voltage source based on the lowest tail voltage. The LED driver can adjust the output voltage so as to maintain the lowest tail voltage at or near a predetermined threshold voltage so as to ensure that the output voltage is sufficient to properly drive each active LED string with a regulated current in view of pulse width modulation (PWM) performance requirements without excessive power consumption.

Abstract:
Power management in a light emitting diode (LED) system having a plurality of LED strings is disclosed. A voltage source provides an output voltage to drive a plurality of LED strings. An LED driver implements a feedback mechanism to monitor the tail voltages of the active LED strings to identify the minimum tail voltage and adjust the output voltage of the voltage source based on the lowest tail voltage. A loop calibration module of the LED driver calibrates the feedback mechanism of the LED driver based on a relationship between a digital code value used to generate a particular output voltage and another digital code value generated based on the minimum tail voltage resulting from the particular output voltage.

Led Driver With Dynamic Headroom Control

View page
US Patent:
8049439, Nov 1, 2011
Filed:
Jan 30, 2009
Appl. No.:
12/363607
Inventors:
Bin Zhao - Irvine CA, US
Jack W. Cornish - Foothill Ranch CA, US
Brian B. Horng - Irvine CA, US
Victor K. Lee - Irvine CA, US
Andrew M. Kameya - Irvine CA, US
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H05B 37/02
US Classification:
315297, 315307, 315308
Abstract:
A voltage source provides an output voltage to drive a plurality of light emitting diode (LED) strings. A LED driver adjusts the level of the output voltage so as to maintain the lowest tail voltage of the LED strings at or near a predetermined threshold voltage so as provide sufficient headroom voltages for current regulators for the LED strings. The LED driver operates in an operational mode and a calibration mode, which can be implemented in parallel with, or part of, the operational mode. During the calibration mode, the LED driver determines, for each LED string, a code value representative of the level of the output voltage necessary to maintain the tail voltage of the corresponding LED string at or near the predetermined threshold voltage. In the operational mode, the code values from the calibration mode are used to control the voltage source to provide an appropriate level for the output voltage.

International Classification:
H05B 37/02
US Classification:
315299, 315185 S, 315308, 315312, 315360
Abstract:
A light emitting diode (LED) system implements a LED driver to drive a set of one or more LED strings. The LED driver includes a voltage source to provide an adjustable output voltage to a head end of each LED string of the set for a first duration and a second duration following the first duration. The LED driver further includes a feedback controller to control the voltage source to adjust the output voltage for the second duration based on a digital code value generated from a minimum tail voltage of one or more tail voltages of the set at a sample point of the first duration. The LED driver further includes a power controller to temporarily enable one or more components of the feedback controller for a sample period of the first duration, the sample period comprising the sample point.

Led Driver With Segmented Dynamic Headroom Control

12/363179
Inventors:
Bin Zhao - Irvine CA, US
Jack W. Cornish - Foothill Ranch CA, US
Brian B. Horng - Irvine CA, US
Victor K. Lee - Irvine CA, US
Andrew M. Kameya - Irvine CA, US
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H05B 37/02
US Classification:
315299, 315185 S, 315308, 315312, 315360
Abstract:
Techniques for dynamic headroom control in a light emitting diode (LED) system are disclosed. An output voltage is provided to drive a plurality of LED strings. A feedback controller monitors the tail voltages of the LED strings to identify the minimum tail voltage and adjusts the output voltage based on the lowest tail voltage. The LED strings grouped into subsets and the feedback controller is segmented such that, for a certain duration, a minimum tail voltage is determined for each subset. The minimum tail voltages of the subsets are used to determine the overall minimum tail voltage of the plurality of LED strings for the certain duration so as to control the output voltage in the following duration. The segments of the feedback controller can be implemented in separate integrated circuit (IC) packages, thereby facilitating adaptation to different numbers of LED strings by integrating the corresponding number of IC packages.

Pulse Width Modulation Frequency Conversion

View page
US Patent:
8188771, May 29, 2012
Filed:
Aug 7, 2009
Appl. No.:
12/537443
Inventors:
Bin Zhao - Irvine CA, US
Andrew M. Kameya - Irvine CA, US
Victor K. Lee - Irvine CA, US
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H03B 19/00
H03K 7/08
US Classification:
327114, 327172, 327175
Abstract:
A pulse width modulation (PWM) frequency converter converts an input PWM signal to an output PWM signal having a different frequency while maintaining a substantially equal duty ratio. The PWM frequency converter samples the input PWM signal for a PWM cycle using a sampling clock. A filter module filters the resulting set of one or more PWM parameters to compensate for noise introduced by potential clock mismatch, clock jitter, ambient variations, and other non-deterministic issues, thereby generating filtered PWM parameters. The sampling employed by the filter module compares a difference between the one or more current PWM parameters and previous (or historical) PWM parameters from an earlier sampled PWM cycle to a predetermined change threshold in determining a filtered set of one or more PWM parameters. The filtered set of one or more PWM parameters then is used to generate one or more corresponding PWM cycles of the output signal.

US Patent:
8279144, Oct 2, 2012
Filed:
Jul 31, 2008
Appl. No.:
12/183492
Inventors:
Bin Zhao - Irvine CA, US
Jack W. Cornish - Foothill Ranch CA, US
Brian B. Horng - Irvine CA, US

Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
G09G 3/32
US Classification:
345 82, 315297
Abstract:
Disclosed are example techniques for frame-based power management in a light emitting diode (LED) system having a plurality of LED strings. A voltage source provides an output voltage to drive the LED strings. An LED driver generates a frame timing reference representative of the frame rate or display timing of a series of image frames to be displayed via the LED system. An update reference is generated from the frame timing reference. The LED driver monitors one or more operating parameters of the LED system. In response to update triggers marked by the update reference, the LED driver adjusts the output voltage of the voltage source based on the status of each of the one or more monitored operating parameters (either from the previous update period or determined in response to the update trigger), thereby synchronizing the updating of the output voltage to the frame rate (or a virtual approximation of the frame rate) of the video being displayed.
