Clean Transition Between Ccm And Dcm In Valley Current Mode Control Of Dc-To-Dc Converter
US Patent:
2011014, Jun 23, 2011
Filed:
Dec 18, 2009
Appl. No.:
12/642542
Inventors:
Yiding (Eric) Gu - Pleasanton CA, US
Hong Ren - San Jose CA, US
Hong Ren - San Jose CA, US
Assignee:
Linear Technology Corporation - Milpitas CA
International Classification:
G05F 1/618
US Classification:
323284
Abstract:
A valley current mode DC-to-DC converter may include an electronic control system configured to cause the DC-to-DC converter to operate under a continuous current mode and a discontinuous current mode. The electronic control system may include a current sensing system configured to sense current traveling through an inductance, a dual threshold generator configured to generate a first and a different second threshold, and a comparator system configured to compare current sensed by the current sensing system with the first threshold when the DC-to-DC converter is operating in the continuous current mode and with the second threshold when the DC-to-DC converter is operating in the discontinuous current mode.
Switching Scheme For Step Up-Step Down Converters Using Fixed Frequency Current-Mode Control
US Patent:
2011027, Nov 17, 2011
Filed:
Apr 18, 2011
Appl. No.:
13/088867
Inventors:
Hong REN - San Jose CA, US
Daniel Long CHEN - San Jose CA, US
Christopher Thomas FALVEY - Fremont CA, US
Daniel Long CHEN - San Jose CA, US
Christopher Thomas FALVEY - Fremont CA, US
International Classification:
G05F 1/10
US Classification:
323234
Abstract:
Novel circuitry and methodology for controlling a step up-step down switching regulator that produces a regulated output signal at an output node in response to an input signal at an input node, and has an inductive device, a plurality of switching circuits for providing connection of the inductive device to the input and output nodes and a ground node, and a switch control circuit for driving the switching devices so as to enable the power supply system to operate in a boost mode to increase the input signal, in a buck mode to decrease the input signal, and in a buck-boost mode when a difference between the input signal and the output signal is within a predetermined range. Buck-boost latch circuitry is provided for latching a transition between the buck mode and the buck-boost mode, or between the boost mode and the buck-boost mode based on a predetermined condition.
