摘要： A voltage regulation system (100) provides a relatively stable voltage source without introducing the typical costs of a ground buffer. The disclosed voltage regulation system (100) includes a voltage regulator (120) that is operative to detect a change of the load current (113) and regulate a current bypass mechanism (130, 140) to stabilize a total supply current (174). For example, the voltage regulator (120) includes a current sensor (140) and a current compensation circuit (130). The current sensor (140) is configure to generate a current compensation signal (132) based on the load current change, whereas the current compensation circuit (130) is configured to adjust a bypass current (133) in response to the current compensation signal (132). As a result, the bypass current (133) dynamically compensates the load current change such that the ground voltage of a variable load (110) becomes relatively stable over a range of load currents.

摘要： A boost control module operates semiconductor switches of a boost converter circuit in an avalanche mode to precharge a boost output capacitor. The boost control module comprises a switching module that complementarily transitions a first semiconductor switch and a second semiconductor switch between ON and OFF states when a current does not exceed a maximum current threshold. The switching module transitions the first semiconductor switch and the second semiconductor switch to the OFF state when the current exceeds the maximum current threshold. The switching module maintains the first semiconductor switch and the second semiconductor switch in the OFF state until at least one of the inductor current is less than or equal to a minimum current threshold.

摘要： A boost converter in which the conventional boost diode is replaced by a bidirectional normally conducting semiconductor switch. The circuit may be implemented so the bidirectional switch is self-driven by connecting a low voltage Schottky diode between a first gate-source terminal pair. An inrush current protection function may be provided by utilizing a second gate-source terminal pair to turn the switch on and off independent of the self-driven operation in response to predetermined excessive load current conditions. The inrush current protection function is implemented by use of a second Schottky diode connected between the second gate and source terminals, and an RC circuit connecting the second gate terminal to the return rail for the converter power output transistor with an externally controlled switch connected to the RC circuit to control the bias according to the load current.

摘要： A voltage regulator circuit (100) includes a first transistor (M1), an inductor (L1), and a diode (D1). The inductor (L1) connects to the diode (D1) at a switch node (SW). The voltage regulator circuit (100) produces an output voltage that is larger than an input voltage. The first transistor (M1) has on and off states and electrically couples a node to ground when in the on state. An error amplifier circuit (140) generates an error signal based on a difference between a reference voltage and a voltage indicative of the output voltage. The error signal causes the first transistor (M1) to transit from the on state to the off state. An adaptive off-time generator circuit (160) couples to an input voltage node, and generates a signal to cause the first transistor (M1) to transit from the off state to the on state. The time the first transistor (M1) in the off state is inversely proportional to the time the first transistor (M1) in the on state.
