  • Patent number: 11863064
    Abstract: According to an aspect, a non-regulated power converter includes a plurality of switching tank converter (STC) modules configured to be connected in parallel and to a load. The plurality of STC modules includes a first STC module configured to generate a first output current and a second STC module configured to generate a second output current. The first STC module includes an output current (OC) measuring circuit configured to measure a value of the first output current, and a dead time (DT) adjustor configured to compare the value of the first output current with a value of a minimum output current provided by the plurality of STC modules. The DT adjustor is configured to adjust a dead time in response to the value of the first output current being greater than the value of the minimum output current.

  • Patent number: 9086710
    Abstract: A compensator circuit includes a first transconductance amplifier to convert an input voltage to a first output current. A second transconductance amplifier converts the input voltage to a second output current. A buffer includes an input and an output. The input of the buffer receives the second output current. A resistance is connected between an output of the first transconductance amplifier and an output of the buffer. A capacitance connected (i) between an output of the second transconductance amplifier and a terminal at a reference potential, and (ii) between the input of the buffer and the terminal. An output voltage of the compensator circuit is based on the first output current and is a voltage across the resistance, the buffer and the capacitance.

  • Patent number: 8629632
    Abstract: The present invention relates to a LED driver that minimizes the driver electronic pin count and integrates the short circuit protection feature. An NPN bipolar transistor is employed in a boost converter configuration to drive a LED string in the backlight display applications. The bipolar transistor is integrated with the driver electronics by two pins. Drive current is injected from the NPN transistor to the LED string to minimizing high voltage connection of each LED string to one.
