Abstract:
Various embodiments of LED drivers and associated methods of are described below. In one embodiment, a method for controlling an LED driver includes receiving a reference voltage, receiving a feedback voltage from said LED driver, receiving said input voltage as a first feed forward voltage and said output voltage as a second feed forward voltage, generating a hysteretic width based on said first feed forward voltage and said second feed forward voltage, and generating a hysteretic band voltage using said hysteretic width and said reference voltage. The method also includes generating a first control signal for controlling said LED driver based on said hysteretic band voltage and said feedback voltage, inverting said first control signal to generate a second control signal for controlling said LED driver, and achieving a generally fixed frequency for said LED driver.

Variable Frequency Timing Circuit For A Power Supply Control Circuit

US Patent:
8531853, Sep 10, 2013
Filed:
Jul 28, 2011
Appl. No.:
13/193434
Inventors:
Stefan Bäurle - San Jose CA, US
Guangchao Darson Zhang - San Jose CA, US
Arthur B. Odell - Morgan Hill CA, US
Edward Deng - Cupertino CA, US
Assignee:
Power Integrations, Inc. - San Jose CA
International Classification:
H02M 3/335
H02M 1/00
H02M 7/757
H02H 7/122
US Classification:
363 78, 363 2118, 363 561, 363 79, 363 80
Abstract:
An example integrated circuit controller includes a pulse width modulation (PWM) circuit and a timing circuit. The PWM circuit controls a switch to regulate an output of a power supply in response to a switch current flowing through the switch and in response to a clock signal having a switching period. The timing circuit provides the clock signal and includes a timing capacitor where the switching period of the clock signal is equal to a charging time that the timing capacitor charges to an upper reference voltage plus a discharging time that the timing capacitor discharges to a lower reference voltage. The timing circuit increases the charging time of the timing capacitor by decreasing a rate at which the timing capacitor is charged to increase the switching period of the clock signal if an on time of the switch is greater than or equal to a threshold time.

Variable Frequency Timing Circuit For A Power Supply Control Circuit

US Patent:
20130336021, Dec 19, 2013
Filed:
Aug 20, 2013
Appl. No.:
13/971605
Inventors:
Guangchao Zhang - San Jose CA, US
Arthur B. Odell - Morgan Hill CA, US
Edward E. Deng - Cupertino CA, US
Assignee:
Power Integrations, Inc. - San Jose CA
International Classification:
H02M 3/335
US Classification:
363 2113, 363 2118
Abstract:
A timing circuit of a controller generates a clock signal having a switching period for use by a pulse width modulation (PWM) circuit to control a switch of a power supply. The switching period of the clock signal is based on a charging time plus a discharging time of a capacitor included in the timing circuit. A first current source charges the capacitor while the timing circuit is in a normal charging mode. A second current source charges the capacitor while the timing circuit is in an alternative charging mode that is when the on time of the switch exceeds a threshold time. The current provided by the second current source is less than the current provided by the first current source such that the switching period of the clock signal is increased in response to the timing circuit entering the alternative charging mode.

US Patent:
20140063862, Mar 6, 2014
Filed:
Nov 13, 2013
Appl. No.:
14/079453
Inventors:
Guangchao Darson Zhang - San Jose CA, US
Arthur B. Odell - Morgan Hill CA, US
Mingming Mao - Saratoga CA, US
Michael Yue Zhang - Mountain View CA, US
Edward Deng - Los Altos CA, US
Assignee:
Power Integrations, Inc. - San Jose CA
International Classification:
H02M 3/335
US Classification:
363 2101
Abstract:
A controller includes a PWM circuit and a timing circuit. The PWM circuit controls a switch in response to a clock signal. A switching period of the clock signal is based on a charging and discharging time of a capacitor included in the timing circuit. Both first and second current sinks discharge the capacitor while the timing circuit is in a normal discharging mode that is when an on time of the switch is less than a threshold time. The second current sink is prevented from discharging the capacitor such that the capacitor is discharged with the first current sink and not the second current sink while the timing circuit is in an alternative discharging mode that is when the on time of the switch exceeds the threshold time. The discharging of the capacitor in the alternative discharging mode increases the switching period of the clock signal.
