摘要： An inventive isolated converter which exempts the auxiliary isolation devices with accurate voltage regulation is disclosed. The converter includes the primary side circuit with a primary controller controlling the on and off of the primary switch and a secondary side circuit with a secondary controller controlling the on and off of the secondary synchronous rectifier. The isolated converter uses the secondary controller to turn on the secondary synchronous rectifier after the secondary current decreases to zero to generate a negative tail current and turns off the secondary synchronous rectifier at a reference tail current peak value to generate a reflected negative current at the primary side circuit for turning on the primary switch.

摘要： A timing circuit operates by applying an arbitrary voltage across a resistance, and using the resulting current to generate a charging current which charges and/or discharges a capacitance to an endpoint voltage. Additional circuitry is arranged such that the capacitance is charged and/or discharged until its voltage crosses a threshold which is proportional to one of the resistance's endpoint voltages, such that the capacitance's endpoint voltage tracks the resistance's endpoint voltage. Thus, the resistor voltage can vary with supply voltage or temperature, or the resistance value itself can vary, without materially affecting the timing relationships. The arbitrary voltage is preferably provided with a pair of diode-connected transistors connected in series with the resistance, so that a single transistor operated at the same current density as one of the diode-connected transistors establishes the threshold voltage and detects when the capacitor voltage reaches the threshold.
摘要翻译：定时电路通过在电阻上施加任意电压来工作，并且使用所得到的电流来产生将电容充电和/或放电到端点电压的充电电流。附加电路被布置成使得电容被充电和/或放电，直到其电压跨过与电阻的端点电压之一成比例的阈值，使得电容的端点电压跟踪电阻的端点电压。因此，电阻电压可以随电源电压或温度而变化，或者电阻值本身可以变化，而不会严重影响时序关系。任意电压优选地设置有与电阻串联连接的一对二极管连接的晶体管，使得以与二极管连接的晶体管中的一个相同的电流密度工作的单个晶体管建立阈值电压并且检测何时电容器电压达到门槛。

摘要： A switched noise filter circuit for DC-DC converters which use the instantaneous output voltage to establish the converter's duty ratio. The converter cycles the switching element on and off for time intervals Ton and Toff, respectively. A switching control circuit includes a filter capacitance connected between the feedback node and ground, and a comparator which compares a feedback voltage Vfb with a fixed voltage Vref; at least one of Ton and Toff is a “modulated” interval which is terminated when Vfb crosses Vref due to the discharge of the filter capacitance. A switched noise filter circuit applies an offset voltage to Vfb during at least one of Ton and Toff, with the offset voltage disconnected from Vfb by the beginning of the modulated interval or shortly thereafter. When the offset voltage is properly applied, the effect of extraneous electromagnetic noise coupled into Vfb is reduced.

摘要： The present invention relates to an electrostatic discharge (ESD) clamp circuit that is used to protect other circuitry from high voltage ESD events. The ESD clamp circuit may include a field effect transistor (FET) element as a clamping element, which is triggered by using a drain-to-gate capacitance and a drain-to-gate resistance of the FET element and a resistive element as a voltage divider to divide down an ESD voltage to provide a triggering gate voltage of the FET element. In its simplest embodiment, the ESD clamp circuit includes only an FET element, a resistive element, a source-coupled level shifting diode, and a reverse protection diode. Therefore, the ESD clamp circuit may be small compared to other ESD protection circuits. The simplicity of the ESD clamp circuit may minimize parasitic capacitances, thereby maximizing linearity of the ESD clamp circuit over a wide frequency range.
摘要翻译：本发明涉及用于保护其它电路免受高电压ESD事件的静电放电（ESD）钳位电路。 ESD钳位电路可以包括作为钳位元件的场效应晶体管（FET）元件，其通过使用FET元件的漏极 - 栅极电容和漏极 - 栅极电阻和电阻元件作为电压来触发以分隔ESD电压以提供FET元件的触发栅极电压。在其最简单的实施例中，ESD钳位电路仅包括FET元件，电阻元件，源极耦合电平移位二极管和反向保护二极管。因此，与其他ESD保护电路相比，ESD钳位电路可能较小。 ESD钳位电路的简单性可以使寄生电容最小化，从而在宽频率范围内最大化ESD钳位电路的线性度。
