    摘要: A resister network having a negative temperature coefficient (NTC) may be utilized to create a temperature compensated equivalent resistance “R” for a current sensing RC network used in measuring inductor current of a DC-to-DC converter or a general switching regulator that needs to use inductor current as a control signal. The NTC resistor of the RC network effectively compensates for the positive temperature coefficient of the switching regulator inductor's inherent DC resistance (DCR). Keeping the time constants of the RC network and the switching regulator inductor substantially matched improves operation of cycle by cycle based control modes such as peak current sensing by the switching regulator controller in performing peak current control for the DC-to-DC converter.

    摘要: A center-tapped transformer includes a spool, a first primary winding unit, and first and second secondary winding units. The spool has a surrounding wall defining a spool axis, and a partition plate unit extending in radial outward directions from the surrounding wall so as to divide the spool into axially extending first and second spool parts. The partition plate unit cooperates with the surrounding wall to define at least one notch. The first primary winding unit surrounds the first spool part and passes through the notch to surround the second spool part. The first and second secondary winding units are disposed on one side of the first primary winding unit and surround the first and second spool parts, respectively.
