Voltage Converters With Reduced Output Frequency Variations And Associated Methods
US Patent:
2012023, Sep 20, 2012
Filed:
Mar 18, 2011
Appl. No.:
13/051360
Inventors:
Yan Dong - San Jose CA, US Peng Xu - San Jose CA, US James H. Nguyen - San Jose CA, US
International Classification:
G05F 3/08
US Classification:
323311
Abstract:
Switch-mode voltage converters and associated methods are disclosed herein. In one embodiment, a switch-mode voltage converter includes a switching transistor coupled between an input voltage (V) and the ground and a controller coupled directly between the input voltage (V) and the ground. The controller is configured to periodically turn on the switching transistor for a generally constant period of time. The controller is further coupled to a DC bias voltage (V) and configured to generate a control current based on the input voltage (V) and the DC bias voltage (V) for generating a switching signal to the switching transistor.
Method And Apparatus For Synchronous Boost Voltage Regulators With Active Negative Current Modulation
US Patent:
7893677, Feb 22, 2011
Filed:
Mar 28, 2008
Appl. No.:
12/057717
Inventors:
James H. Nguyen - San Jose CA, US
Assignee:
Monolithic Power Systems, Inc. - San Jose CA
International Classification:
G05F 1/575
US Classification:
323284, 323223
Abstract:
A switch-mode synchronous boost voltage regulator is disclosed that includes a boost voltage regulator and an active current modulator. The active current modulator detects a negative current flowing through the high-side switch during a light load condition. When the negative current is detected, the active current modulator is operable to maintain the high-side switch “on” in a linear mode and to limit the negative current to a predetermined current level.
Optimal Control Of Wide Conversion Ratio Switching Converters
US Patent:
6940733, Sep 6, 2005
Filed:
Aug 22, 2003
Appl. No.:
10/646450
Inventors:
David Chalmers Schie - Cupertino CA, US Alexander Mednik - Campbell CA, US James Hung Nguyen - San Jose CA, US Sang Ton Ngo - Cupertino CA, US Khai Minh Le - Saratoga CA, US Wei Gu - San Jose CA, US Larry Kerenyi - White Plains NY, US
Assignee:
Supertex, Inc. - Sunnyvale CA
International Classification:
H02M003/335
US Classification:
363 2112, 363 71
Abstract:
A switch state controller generating a pulse train is used in a power converter utilizing a plurality of converter stages all simultaneously controlled by a single switch controlled by said pulse train. On time of the pulse train is controlled according to an input or interim node characteristic of the supply and period is controlled by a characteristic of the output of the converter. This allows development of AC-to-DC converters, including power-factor-correction converters, and DC to DC converters with high conversion ratio with minimal parts count & high reliability.
