摘要： A voltage-waveform detector produces a voltage-feedback signal and a discharge-time signal by multi-sampling a voltage signal of a transformer. The discharge-time signal represents a discharge time of a secondary-side switching current. A voltage-loop error amplifier amplifies the voltage-feedback signal and generates a control signal. An off-time modulator correspondingly generates a discharge-current signal and a standby signal in response to the control signal and an under-voltage signal. The under-voltage signal indicates a low supply voltage of the controller. An oscillator produces a pulse signal in response to the discharge-current signal. The pulse signal determines the off-time of the switching signal. A PWM circuit generates the switching signal in response to the pulse signal and the standby signal. The standby signal further controls the off-time of the switching signal and maintains a minimum switching frequency. The switching signal is used for regulating the output of the power supply.

摘要： A multiple-sampling circuit is proposed for measuring a voltage signal and a discharge time of a transformer. Sampling signals are used for generating hold voltages by alternately sampling the reflected voltage from the transformer. A buffer amplifier generates a buffer voltage from the higher voltage of hold voltages. A sampling switch periodically conducts the buffer voltage to produce a voltage-feedback signal. The voltage-feedback signal is proportional to an output voltage of the switching circuit. A threshold signal added to the reflected voltage signal produces a level-shift reflected signal. A discharge-time signal is generated as the switching signal is disabled. The discharge-time signal is disabled once the level-shift signal is lower than the voltage-feedback signal. The pulse width of the discharge-time signal is therefore correlated to the discharge time of the transformer. The sampling signals are enabled to generate hold voltages only when the discharge-time signal is enabled.
摘要翻译：提出了一种多采样电路，用于测量变压器的电压信号和放电时间。采样信号用于通过交替采样来自变压器的反射电压来产生保持电压。缓冲放大器从保持电压的较高电压产生缓冲电压。采样开关周期性地进行缓冲电压以产生电压反馈信号。电压反馈信号与开关电路的输出电压成比例。添加到反射电压信号的阈值信号产生电平移位反射信号。随着切换信号被禁止，产生放电时间信号。一旦电平移位信号低于电压反馈信号，放电时间信号被禁止。因此，放电时间信号的脉冲宽度与变压器的放电时间相关。采样信号仅在放电时间信号使能时才能产生保持电压。

摘要： A power-mode control circuitry is presented for power converters to precisely control a maximum of the output power. The power-mode control circuitry includes a filter to convert a switching current into an average-current signal. A voltage divider attenuates an input voltage of the power converter to an average-voltage signal. A multiplier produces a power signal by multiplying the average-current signal with the average-voltage signal. An error amplifier generates a programming signal by comparing the power signal with a power-level threshold. The programming signal further controls the switching signal for achieving power-mode control.
