Dc-To-Dc Converter With Improved Transient Response

View page
US Patent:
6459602, Oct 1, 2002
Filed:
Apr 25, 2001
Appl. No.:
09/843200
Inventors:
Laszlo Lipcsei - San Jose CA
Assignee:
O
International Classification:
H02M 75387
US Classification:
363132, 363 98, 323288
Abstract:
A DC to DC converter includes a comparator, a driver, and a pair of switches. The comparator compares the output voltage with a reference voltage signal and generates a PWM signal. The driver drives the switches so as to force the output voltage to follow the reference signal. In a multiphase architecture, two or more such converter circuits are incorporated to minimize the output voltage ripple and further reduce the recovery time. In a two-phase architecture, two reference signals are phase-shifted by 180 degrees. In an N-phase architecture, the reference signals are phase-shifted by 360/N degrees.

Dc-To-Dc Converter With Improved Transient Response

US Patent:
6813173, Nov 2, 2004
Filed:
Jun 26, 2003
Appl. No.:
10/606537
Inventors:
Laszlo Lipcsei - San Jose CA
Assignee:
02Micro International Limited - Grand Cayman
International Classification:
H02M 75387
US Classification:
363 98, 363132, 323288, 323282
Abstract:
A DC to DC converter having improved transient response, accuracy, and stability. The DC to DC converter includes a first comparator configured to compare a first signal with a second signal. The first signal has a DC offset determined, at least in part, by a DC reference voltage source. The second signal is representative of an output voltage level of the DC to DC converter. The comparator is further configured to provide a control signal to a driver based on a difference between the first signal and the second signal, the driver driving the output voltage of the DC to DC converter. The DC to DC converter further includes an accuracy circuit to enhance accuracy of the DC to DC converter. The DC to DC converter may further include a stability circuit to enhance stability of the DC to DC converter.

Controller For Dc To Dc Converter

View page
US Patent:
6844710, Jan 18, 2005
Filed:
Sep 23, 2003
Appl. No.:
10/668459
Inventors:
Laszlo Lipcsei - San Jose CA, US
Assignee:
O2Micro International Limited - Grand Cayman
International Classification:
G05F 144
US Classification:
323284, 323285
Abstract:
A switching circuit includes at least one switch, and a controller configured to provide a periodic control signal. The switch is responsive to the periodic control signal to change states with a start of each period, and a frequency of the periodic control signal has a predetermined minimum frequency level greater than an audible frequency limit for humans. The switching circuit may be used to control a high side switch and a low side switch in a DC to DC converter. A controller having an input voltage sensing circuit to sense an input of a DC to DC converter without using an additional input pin is also provided. Related methods are also provided. A dual phase controller having a phase selection circuit to select between phases is also provided.

Controller For Dc To Dc Converter

View page
US Patent:
6965221, Nov 15, 2005
Filed:
Mar 14, 2003
Appl. No.:
10/389037
Inventors:
Laszlo Lipcsei - San Jose CA, US
Assignee:
O2Micro International Limited - Grand Cayman
International Classification:
G05F001/40
US Classification:
323283, 323224, 323285
Abstract:
A controller for a DC to DC converter is configured to provide a PWM signal in a first state during a first time interval based on an input voltage less a voltage level representative of an output voltage of the DC to DC converter. The controller may provide the PWM signal in the first state based on the time it takes to charge an energy storage element of the controller to a predetermined level. The controller may also provide an estimator of a zero inductor current level in an associated inductor when the energy storage element is completely discharged. The controller may also be a digital controller that counts time pulses to provide the PWM signal. A DC to DC converter including such a controller and associated methods are also provided.

Battery Over Voltage And Over Protection Circuit And Adjustable Adapter Current Limit Circuit

View page
US Patent:
6989981, Jan 24, 2006
Filed:
Oct 24, 2002
Appl. No.:
10/279345
Inventors:
Vlad Popescu-Stanesti - San Jose CA, US
Laszlo Lipcsei - San Jose CA, US
Stephen Gustafson - Round Rock TX, US
Assignee:
02Micro International Limited - Grand Cayman
International Classification:
H02H 9/08
US Classification:
361 939, 361 911
Abstract:
A battery charging circuit is disclosed that includes protection circuitry and/or adapter current limit offset circuitry. The protection circuitry is operable to reduce or eliminate an overvoltage and overcurrent condition generated by a charge controller when a charging path is an open circuit, for example, when a battery is disconnected from the charging path. The adapter current limit offset circuitry is operable to generate an offset signal to an adapter current signal utilized by a charger controller.
