A thermally compensated current sensor is connected to an intrinsic current sensing element exhibiting a temperature-based parameter non-linearity. The thermally compensated current sensor has a temperature coefficient that substantially matches a temperature coefficient of an intrinsic power converter element used to measure current flow, thus linearizing the current measurement.

摘要： The integrated control circuit is for an electronic circuit, such as a DC-to-DC converter, using current sense information developed across an intrinsic circuit element of the electronic circuit. The integrated control circuit includes a temperature sensor to sense a temperature rise induced by the intrinsic circuit element of the electronic circuit. The temperature error signal and a feedback signal from the intrinsic circuit element of the converter are combined to provide a temperature-corrected feedback signal to a control unit for the converter.

摘要： A semi-clockless, cascaded, current-mode regulator has a first regulator that receives a clock signal from a controller. By ‘semi-clockless’ is meant that a clock signal is applied to the first of a cascaded plurality of regulators, and that as a result of the cascading of clock delay circuits in each of the regulators, the remaining regulators receive sequentially delayed versions of the clock signal applied to the first regulator. The regulators are coupled to control the operations of associated pulse width modulation controlled switching circuits. Outputs of the switching circuits are combined to realize a multi-phase output voltage.

摘要： A cascadable power regulator including a programmable delay unit and PWM control logic. The programmable delay unit initiates a delay period in response to a digital input signal and asserts a digital output signal upon expiration of the delay period. The PWM control logic controls a PWM cycle in response to the digital input signal and in response to an output control condition. The cascadable regulator uses digital signals to communicate between channels. Digital signals are not prone to the same kind of signal degradation or noise susceptibility as analog signals. Thus, the number of phases is not limited, the physical separation between the regulators is not limited, and the switching frequency is not as limited. There is no clock signal from a separate controller so that the controller is a relatively simple, low-cost device. Since there is no clock, a unique self-oscillating system is achieved using the cascadable regulator.
