    • Methods and apparatus for managing a source image that is output in a rotated or skewed orientation to a raster buffer. The source image includes a plurality of source samples arranged in source rows having a source direction. The raster buffer is oriented in a destination space and receives the rotated or skewed image as a series of samples in rows defined by a destination direction. The raster buffer provides rows of samples to a rendering device for rendering scan lines for output on a raster device. The method includes determining an angle between the source direction and the destination direction and adjusting the organization of the source samples to align source samples in scan rows where each scan line can be rendered from the raster buffer using at most a predetermined small number of scan rows.

    • A flyback converter uses primary side sensing to sense the output voltage for regulation feedback. A comparator on the primary side detects whether the output voltage has exceeded a predetermined regulated voltage by a first threshold to detect an over-voltage condition, resulting from a current generated by the converter exceeding the load current. Triggering of the comparator causes the converter to enter a non-switching sleep mode, whereby the output voltage droops over a period of time. When the output voltage has drooped below the predetermined regulated voltage by a second threshold, a synchronous rectifier is controlled to turn on, then off, to generate a pulse in the primary winding. Upon detection of the pulse, the sleep mode is terminated, and normal operation resumes until a regulated voltage is achieved or until the first threshold is again exceeded by the output voltage.
    • 反激转换器使用初级侧感测来检测输出电压以进行调节反馈。 初级侧的比较器检测输出电压是否超过预定的调节电压第一阈值,以检测由转换器产生的电流超过负载电流导致的过电压状况。 比较器的触发使得转换器进入非切换睡眠模式,由此输出电压在一段时间内下降。 当输出电压下降到低于预定调节电压第二阈值时,同步整流器被控制为接通,然后关断,以在初级绕组中产生脉冲。 当检测到脉冲时,停止睡眠模式,并且恢复正常操作,直到达到稳定电压或直到输出电压再次超过第一阈值为止。
