The second switch controller adjusts a second activation timing of a second control signal in response to the pulse width modulation signal, the first control signal, and a second control signal. The second control signal is a signal for controlling the second switch. | 02-04-2016 |
20160087462 | CHARGER CIRCUIT INCLUDING A PLURALITY OF CHARGING PATHS - A charger circuit includes a first path regulator, a path switch, and a second path regulator. The first path regulator is configured to generate a first regulation current based on an input voltage and an input current. The path switch is configured to pass or block a first charging current in response to a control signal. The first charging current is generated based on the first regulation current. The second path regulator is configured to generate a second regulation current based on the input voltage and the input current. At least one of the first charging current and a second charging current is used to charge a battery. The second charging current is generated based on the second regulation current. The second charging current is transferred to the battery without passing through the path switch. | 03-24-2016 |

20140253073 | BI-DIRECTIONAL VOLTAGE POSITIONING CIRCUIT, VOLTAGE CONVERTER AND POWER SUPPLY DEVICE INCLUDING THE SAME - A bi-directional voltage positioning circuit includes a voltage to current converter, a current mirror circuit and a switch. The voltage to current converter converts a sensing voltage to a first current, and the sensing voltage is sensed based on a current flowing through an output coil connected between a switching node and an output node. The current mirror circuit mirrors the first current to generate a second current and a third current, the second current is N times greater than the first current, the third current is M times greater than the first current, and N and M are real numbers greater than zero. The switch provides a feedback node with one of the second current and third current in response to a switching control signal, and an output voltage of the output node is divided at the feedback node. | 09-11-2014 |
