摘要： A dual polarity voltage regulator circuit that is capable of regulating either positive or negative voltages is disclosed. The regulator circuitry of the present invention provides dual polarity regulation while requiring only one additional pin over a single polarity regulator. The present invention utilizes a single error amplifier, a negative feedback network, and an overshoot recovery circuit in providing dual polarity regulation. One advantage of the negative feedback network of the present invention is that the regulator circuit uses the same error amplifier (i.e., only one error amplifier) to regulate both positive and negative input voltages. The negative feedback network actively affects signals input into the error amplifier during negative regulation, but is essentially disabled during positive regulation. Thus, positive and negative voltage regulation are provided using a single error amplifier that retains its multiple functions (for example, oscillator frequency shifting, overshoot improvement and loop frequency compensation).
摘要翻译：公开了能够调节正或负电压的双极性调压电路。本发明的调节器电路提供双极性调节，同时在单个极性调节器上仅需要一个附加引脚。本发明利用单误差放大器，负反馈网络和过冲恢复电路来提供双极性调节。本发明的负反馈网络的一个优点是调节器电路使用相同的误差放大器（即，仅一个误差放大器）来调节正输入电压和负输入电压。负反馈网络在负调节期间主动影响输入到误差放大器的信号，但在正调节期间基本上禁用。因此，使用保持其多个功能的单个误差放大器（例如，振荡器频率偏移，过冲改善和环路频率补偿）来提供正和负电压调节。

摘要： Circuits and methods are provided for increasing the turn-off switching speed of a high-speed integrated circuit, bipolar switching regulator. The regulator The circuit runs at megahertz frequencies, yet is efficient as previously available bipolar integrated circuit switching regulators operating at much lower frequencies. The increased speed switch turn-off circuitry prevents the switch from spending too much time in a high power state (which would slow the switch down), increases the stability of the switch as compared with previously known designs. In a preferred embodiment, the circuitry includes a PNP transistor and a diode-connected transistor with their base-emitter circuits coupled to form a loop with the base-emitter circuit of a NPN transistor and the base-collector circuit of the switch to limit the on state voltage of the switch and control its depth of saturation. A capacitor is connected across the diode-connected transistor to reduce instabilities due to ringing caused by delays in the feedback loop.

摘要： An integrated circuit for use in implementing a switching voltage regulator, the integrated circuit including a power switching transistor, driver circuitry and control circuitry, which is operable in a normal feedback mode or an isolated flyback mode. The integrated circuit includes shutdown circuitry for placing the regulator in a micro-power sleep mode, and can be packaged in a five-pin conventional power transistor package. The terminals of the integrated circuit regulator perform multiple functions. A compensation terminal is used for frequency compensation, current limiting, soft-start operation and shutdown. A feedback terminal is used as a feedback input when the integrated circuit is in feedback mode, and as a logic pin to program the regulator for isolated flyback operation. The feedback terminal is also used to trim the flyback reference voltage.
