Apparatus And Method For Start-Up For A Synchronous Switching Regulator

View page
US Patent:
7045992, May 16, 2006
Filed:
Jun 22, 2004
Appl. No.:
10/873832
Inventors:
Faruk Jose Nome Silva - Sunnyvale CA, US
Kwok-Fu Chiu - San Jose CA, US
Barry Culpepper - Sunnyvale CA, US
Michael J. Wurtz - St. Paul MN, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
G05F 1/656
G05F 1/652
US Classification:
323222, 323223, 323224
Abstract:
A synchronous switching voltage regulator circuit is provided. After the first PWM pulse or at the end of a soft-start, a gradual transition is made from asynchronous rectification to fully synchronous rectification. The gradual transition to synchronous rectification is made by gradually increasing the time that the synchronous switch is enabled to be on.

Apparatus And Method For Dual Features Of Frequency Setting And Frequency Synchronization In One Pin

US Patent:
7196589, Mar 27, 2007
Filed:
Oct 21, 2004
Appl. No.:
10/971502
Inventors:
Faruk Jose Nome Silva - Sunnyvale CA, US
Kwok-Fu Chiu - San Jose CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
H03B 5/24
H03K 3/02
US Classification:
331 49, 331143, 331153, 331173
Abstract:
An integrated circuit includes an oscillator circuit, where a frequency of an oscillator output signal provided by the oscillator circuit is adjustable by either coupling a resistor to an input pin, or by applying an external clock signal to the input pin. The oscillator circuit includes a comparator, a follower, a current-controlled oscillator, and a switch circuit. The switch circuit is coupled between the input pin and a node that is coupled to the current-controlled oscillator. Also, the follower is arranged to cause the voltage at the node to be at a pre-defined voltage unless the voltage at the node is overdriven by an external clock signal. The comparator circuit is arranged to determine whether the signal at the input pin is a clock signal. If it is determined that the signal at the input pin is a clock signal, the switch circuit is opened.

Glitch-Free Start-Up With A Tracking Pin

US Patent:
7498874, Mar 3, 2009
Filed:
Aug 3, 2006
Appl. No.:
11/462311
Inventors:
Faruk J. Nome - Sunnyvale CA, US
Jeff Lee Nilles - Los Altos CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
H03F 1/02
US Classification:
330 9, 327124
Abstract:
An error amplifier for closed loop operation is provided. The error amplifier has a track input and a feedback input. During soft-start, a voltage offset is added to the error amplifier input. In one embodiment, the voltage offset is gradually removed during the soft-start.

Apparatus And Method For Reverse Current Correction For A Switching Regulator

View page
US Patent:
7598715, Oct 6, 2009
Filed:
Apr 4, 2007
Appl. No.:
11/696648
Inventors:
George A. Hariman - Sunnyvale CA, US
Faruk Jose Nome Silva - Sunnyvale CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
G05F 1/59
US Classification:
323271, 323222, 323285
Abstract:
A synchronous switching voltage regulator circuit is provided. After the first PWM pulse or at the end of a soft-start, a gradual transition is made from asynchronous rectification to fully synchronous rectification, or vice versa. During the gradual transition, the error voltage is level-shifted down to correct for error caused by reverse current through the body diode of the main switch.

Apparatus And Method For Faster Unloading Of Transient Response In A Synchronous Buck Switching Regulator

View page
US Patent:
7705579, Apr 27, 2010
Filed:
Jan 14, 2008
Appl. No.:
12/014014
Inventors:
George A. Hariman - Sunnyvale CA, US
Faruk J. Nome - Sunnyvale CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
G05F 1/575
G05F 1/618
US Classification:
323284, 323285
Abstract:
A synchronous buck regulator controller is provided. The regulator controller includes switch control circuitry, an unloading event detection circuit, an inductor current detection circuit, and a synchronous switch control logic circuit. In operation, the regulator controller controls a main switch and a synchronous switch to control the buck regulation. The unloading event detection circuit is arranged to detect an unloading event, and to assert an unloading event signal if such an event is detected. The inductor current detection circuit is arranged to assert an inductor current detection signal if the inductor current is close to zero. The synchronous switch control logic circuit is arranged to block the synchronous switch from turning on if the unloading event signal is asserted and the inductor current detection signal is not asserted. However, if the inductor current detection signal is subsequently asserted while the unloading event signal is still asserted, the synchronous switch control logic circuit stops blocking the synchronous switch from turning on.

US Classification:
323222, 323223, 323224, 323226
Abstract:

Instantaneous Average Current Measurement Method

View page
US Patent:
8587275, Nov 19, 2013
Filed:
Feb 9, 2011
Appl. No.:
13/024013
Inventors:
Faruk Jose Nome Silva - Sunnyvale CA, US
Karen Chan - South San Francisco CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
G05F 1/00
US Classification:
323282, 323240, 323242, 323284, 323285, 323288
Abstract:
Circuitry and method for providing a signal indicative of instances of conduction of average inductor current in a DC-to-DC voltage converter. Such signal identifies a time when the instantaneous average current being conducted by the inductor in a DC-to-DC voltage converter can be measured by providing a signal edge approximately halfway through one of the increasing and decreasing current conduction intervals of the inductor.

Quasi-Feedforward Pwm Modulator

View page
US Patent:
6930526, Aug 16, 2005
Filed:
Dec 4, 2003
Appl. No.:
10/728592
Inventors:
Faruk Jose Nome Silva - Sunnyvale CA, US
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
H03K003/017
US Classification:
327175, 327198, 327 31, 323274, 323288
Abstract:
Devices, circuits, and methods generate a substantially constant output voltage. A power storage element generates a DC output voltage from an input voltage. The output is sampled to generate a feedback signal. An error amplifier generates an error signal from the feedback signal and a reference voltage. A ramp generator generates a ramp signal from the error signal. A comparator generates a pulse signal by comparing the ramp signal to a threshold voltage. The pulse signal is used to control a power switch, which switches the power storage element on and off. The pulse signal is generated such that, if the input voltage changes within a certain range, a width of its pulses changes so as to maintain the output voltage substantially constant.
