摘要： A programmable voltage regulator configurable for reverse blocking and double power density is disclosed herein. The programmable voltage regulator includes an error amplifier that couples to receive a reference voltage. A first NMOS pass transistor connects between an auxiliary voltage input node and the output terminal of the voltage regulator, wherein the first NMOS pass transistor is biased by the output of the error amplifier. Connected between the source of the first NMOS pass transistor and the second input of the error amplifier, a feedback network provides feedback for the voltage regulator. A second NMOS pass transistor connects between the first power supply and the auxiliary voltage input node. Furthermore, an independent node control circuit biases the second NMOS pass transistor such that in a first mode of operation, a first control signal input is operable to receive a signal for controlling the second NMOS pass transistor during reverse battery condition. In a second mode of operation, independent node control circuit includes a second control signal input that is operable to couple to the output terminal of the error amplifier while simultaneously the first power supply rail is operable to couple to the output terminal of the voltage regulator to provide double power density.

摘要： An integrated circuit (10) is disclosed comprising a fundamental frequency oscillator comprising a reference node (32) whose voltage varies between a high threshold and a low threshold. The fundamental frequency oscillator is operable to generate a first output at the fundamental frequency on a first output node (36). The integrated circuit (10) also comprises a circuit (C2) coupled to the reference node. The circuit (C2) is operable to sense the voltage at the reference node (32), to determine when the voltage exceeds an intermediate threshold between the high threshold and the low threshold, and to generate a second output in response to the determination. The integrated circuit (10) also comprises logic (40) coupled to the circuit (C2) and load circuitry (50) coupled to the logic (40). The logic (40) is operable to generate an output signal at an output frequency greater than the fundamental frequency in response to the second output and the first output.
