Abstract: A fly-back converter and method of operating is provided to eliminate cross-conduction between a power-switch (PS) on a primary side of a transformer and a synchronous-rectifier (SR) on a secondary side when operating in continuous conduction mode. Generally, the method includes turning on the SR when a drain voltage of the SR drops to a negative voltage followed by a rise in the SR-drain-voltage at a first slope as a current is drawn from the secondary side of the transformer through the SR. When the PS is turned on before the transformer is completely discharged cross-conduction causes a change in the rise of the drain voltage to a second slope greater than the first slope. By turning off the SR within 50 ns of the change in the rise of the drain voltage, cross-conduction is minimized or eliminated without receiving turn-on information from a controller operating the PS.

Abstract: An integrated circuit includes a capacitive sensing circuit to receive signal values associated with a proximity distance to an object. A pair of low pass filters (LPFs) are coupled in parallel to the capacitive sensing circuit and include a first LPF configured with a low filtering rate and a second LPF configured with high filtering rate that is higher than that of the low filtering rate. Control logic is coupled to the pair of LPFs and estimates the proximity distance based on one or more filtered signal values received from the pair of LPFs. The logic causes the second LPF to filter the signal values while the proximity distance remains unchanged. The logic detects a change in the proximity distance beyond a threshold value. The logic causes the first LPF to filter a subsequent signal value received from the capacitive sensing circuit based on detecting the change.
