摘要： The reference voltage generator for a switch mode regulator includes: a reference voltage source; a soft-start voltage generator; and a comparator having a directional offset for comparing an output of the reference voltage source with an output of the soft-start voltage generator. Because of the intentional directional offset, the pass switch does not turn ON during the transition from the ramp voltage to reference voltage, therefore reducing energy stored in the inductor. Thus the voltage overshoot is reduced during the end of the soft-start cycle.

摘要： A current monitor (360) having a high performance, simple, and cost effective design that is independent of process, temperature and voltage is disclosed herein. The current monitor (360) includes a sensing transistor (340) that couples to the main transistor (312) of an adjoining voltage regulator. Specifically, the control and source nodes of each transistor couple to each other, respectively. The size of the main transistor (312) is a predetermined multiple integer n of the size of the sensing transistor. A first resistor (RS3) couples between a supply voltage and the drain node of the main transistor (312). A second resistor (RS1) couples between a supply voltage and the drain node of the sensing transistor (340), wherein the size of the second resistor (RS1) is equal to the size of the first resistor (RS3) multiplied by the predetermined multiple integer n. An inverting input of an amplifier (342) couples to the drain node of the sensing transistor (340), while a third resistor (RS2) connects between the supply voltage and a non-inverting input of the amplifier (342). The amplifier (342) drives a transistor (344) within a closed feedback loop to equalize the value of the voltages at both inputs of the amplifier (342). A feedback resistor (Rfdb2) coupled between the source node of the transistor (344) and ground. A comparator (348) connects to the source node of the transistor (344) and between a current source and a reference resistor (Rref) to provide an output voltage.

摘要： The present invention provides a system for producing high voltage, low power driver circuitry (300) that addresses a number of disparate design requirements. The present invention provides circuitry comprising a voltage supply (308) and an output node (302). A transistor (304) is provided. A first resistive element (312) is coupled to the voltage supply, while a second resistive element (314)—having a resistance value equal to that of the first resistive element—is coupled between a second terminal of the transistor and the output node. A first diode (310) is coupled to the first resistive element and to a first terminal of the transistor. A clamping system (316) is coupled to the transistor, and a current limiting system (318) is coupled to the clamping system.
