    摘要: Various systems, methods and apparatuses are provided herein for limiting power dissipation in a switch. As one example, a method for limiting power dissipation is disclosed. The method includes monitoring current through the switch, and based at least in part on detecting that the current is at least as great as a predetermined current limit, regulating the current to the predetermined current limit. The method also includes measuring an amount of power dissipated in the switch while the current is being regulated, and opening the switch when the amount of power has reached a predetermined power limit.

    摘要: A switching regulator generally includes an output circuit, a comparator, an on-time timer and an error amplifier. The output circuit receives an input voltage and produces an output voltage. The comparator causes the output circuit to turn on the output voltage when a feedback voltage falls below a first reference voltage. The on-time timer causes the output circuit to turn off the output voltage after a time-out period. The error amplifier receives the feedback voltage and a second reference voltage and produces the first reference voltage.

    摘要: A feedback-controlled battery charger circuit (500) provides, alternatively, constant current and constant voltage to a battery (328) being charged. Current and voltage at the charger output (326) are sensed in sensing elements (308) and compared to preset reference values from reference generators for current (330) and voltage (332), thus generating error signals for both current and voltage. These error signals are amplified in separate amplifiers (530, 534); then, depending on battery voltage, one of the amplified error signals is automatically selected by a signal selector (540). The selected error signal is applied to a single compensation amplifier (554) with reactive feedback loop (552, 556); the output of the compensation amplifier with feedback (504) then controls the output current or voltage of the output stage (306). This output stage is a voltage controlled current source. The output of this voltage controlled current source is connected through an output filter (318) and sensing elements (308) to the battery (328) being charged.

    摘要: Provided is a method of operating a charge-pump, which may be implemented in IC devices such as digital signal processors (DSPs) and mixed signal analog circuits. The method includes the steps of charging a first capacitor, and then choosing between two switching sequences based on the relative values of the input voltage and the output voltage. When the input voltage is determined to be greater than the output voltage, the method applies a first switching sequence to discharge the first capacitor into a second capacitor by first partially discharging the first capacitor into the second capacitor, then fully discharging the first capacitor into the second capacitor. When the input voltage is determined to be less than or equal to the output voltage, the method uses a second switching sequence to prevent the discharge of the second capacitor into the first capacitor by electrically isolating the first capacitor.
