    摘要： A lithium battery control circuit and a lithium battery charger are provided. The lithium battery charger includes the lithium battery control circuit. The lithium battery control circuit includes a smooth transition circuit and an off-time control circuit. The smooth transition circuit generates a first voltage according to a sense current signal and a feedback signal, and generates a second voltage according to a mode signal. The smooth transition circuit compares the first voltage with the second voltage to generate a reset signal. The off-time control circuit converts the feedback signal to generate a first current by a voltage-to-current mechanism, and generates a set signal by using the first current and a duty ratio signal. The invention can prevent a surge current and an oscillation phenomenon by the smooth transition circuit. A switching frequency and a ripple size of an output current are controlled by the off-time control circuit.

    摘要： A system according to examples of the present disclosure includes a battery charger electrically coupled to a battery and a battery charging circuit. The battery charging circuit includes an operational amplifier having a negative input to receive a pre-bias voltage, a positive input, an output, and a voltage offset. The battery charging circuit also includes a charge controller having an analog-to-digital converter to receive a voltage output from the output of the operational amplifier and a voltage supply to supply a voltage input into the positive input of the operation amplifier to cancel the voltage offset of the operational amplifier. In the example, the voltage output of the charge controller is a function of the voltage input of the charge controller.

    摘要： In a lighting device, each of n circuit blocks includes a current controller, a storage element, a charging current controller, a charging rectifier element, and a discharging rectifier element. A first circuit block of the n circuit blocks is configured such that a pulsating voltage generated by rectifying a sine wave AC voltage is applied to the series circuit of the current controller and one light source electrically connected to the first circuit block. An i-th circuit block of the n circuit blocks is electrically connected in parallel to the current controller of an i-1-th circuit block via an i-1-th connection rectifier element.
