Latest Patents
Keesor's latest patents include innovative solutions such as "Automatic dropout prevention in LED drivers." This invention provides a system and method for preventing a dropout of an LED current. The system comprises a voltage source, a first circuit, a second circuit, a controller, and at least one LED. The first circuit receives a reference voltage and set-point current data to produce a threshold voltage, which is then used to manage the output current through the LED. The controller determines if a dropout has occurred and adjusts the current accordingly.
Another significant patent is the "Method and apparatus for a charge pump DC-to-DC converter having parallel operating modes." This invention allows a DC-to-DC converter to operate in multiple modes, including a dual mode where both linear pass and charge pump output circuits work in parallel. This dynamic switchover enhances efficiency based on changing operating conditions, such as input and output voltages.
