The frequency monitoring system may be configured to determine the operating frequency of the clock, and based at least on (a) the operating frequency of the clock and (b) the measured temperature associated with the electronic device, generate a corrective action signal to initiate a corrective action associated with the electronic device or a related device. The temperature sensor, clock, and frequency monitoring system may, for example, be provided on a microcontroller.

摘要： A number of standard PWM generators produce PWM signals that may be used to drive the power stages for Full-Bridge, Feed-Forward, Push-Pull, Phase-Shift Zero Voltage Transition (ZVT), and other switched mode power supply (SMPS) conversion topologies. These PWM signals may be fed to logic functions of a combinatorial logic block. Appropriate PWM signals are selected as operands along with desired logic function(s) that operates on these input operands. The resultant combinatorial PWM signals may then be used directly or may be fed through dead-time processing circuitry prior to outputting to an application circuit. In addition to the combinatorial logic functions, sequential logic functions may also be used to provide sequential PWM signals, e.g., synchronous sequential, asynchronous sequential, and/or sequential-combinatorial PWM signals.

摘要： A phase accumulator style circuit generates an output stream of pulses. The density of the pulse stream is proportional to the input data value relative to the maximum value supported by the bit width of an adder. The output pulse density is representative of the desired output voltage. The pulse stream may be filtered with a resistor-capacitor (RC) low pass filter to yield an analog voltage. Faster clock rates support the use of smaller output filters that reduce circuit cost. This circuit provides triangle wave generation wherein the DAC output ramps up and down at a user specified rate (slope) between user specified maximum and minimum amplitude values. The up and down triangle wave ramp rates (up and down slopes) may be different and independent or the same.

摘要： Power supply modules have outputs coupled in parallel and convey load share balancing information over a single wire load share bus. Pulse width modulation (PWM) signals represent output loading of each of the power supply modules over the single wire load share bus. The PWM load share signal width (time asserted) of the PWM signal represents the output loading of the respective power supply module. Each of the power supply modules detect the assertion of the PWM signal on the load share bus and then each of them simultaneously drive the load share bus with a PWM signal representing their respective output loading. The power supply module having the greatest percent loading will assert its PWM load share signal longest, and the other power supply modules will thereafter adjust their outputs to more evenly supply power outputs to the load.

摘要： Groups of phase shifted Pulse Width Modulation signals are generated that maintain their duty-cycle and phase relationships as a function of the period of the PWM signal frequency. The multiphase PWM signals are generated in a ratio-metric fashion so as to greatly simplify and reduce the computational workload for a processor used in a PWM system. The groups of phase shifted PWM signals may also be synchronized with and automatically scaled to match external synchronization signals.
