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： A method of improving efficiency in a boost regulator circuit includes the steps of transferring energy stored in a load to an energy storage component and transferring energy back from the energy storage component to the load. This method may be actuated in a boost regulator circuit having a first energy storage component, means for initiating and discontinuing energy storage in the first energy storage component, a capacitive load, a bi-directional drive circuit coupled to the first energy storage component, a second energy storage component coupled to the drive circuit, and means for transferring energy between the capacitive load and the second energy storage component, wherein when the voltage having a first polarity across the capacitive load reaches a predetermined voltage it transfers the energy in the capacitive load to the second energy storage component and subsequently transfers the energy back to the capacitive load in the second polarity, thereby conserving energy and substantially reducing power consumption of the boost regulator circuit.

摘要： System and method for controlling current across a load. A preferred embodiment comprises a current varying circuit (such as current varying circuit 525) that can create a sequence of voltage drops in a driver circuit (such as the driver circuit 505) coupled to an inductive load (such as the inductive load 535). By initially producing a large voltage drop and then stepping the voltage drop down gradually, the current in the inductive load can be rapidly removed without producing a current undershoot, which, in certain applications, can result in unwanted noise and vibration.
