摘要： An electronic control unit (100) suitable for a motorcycle (101) provides diagnostic support, tachometer drive and warning lamp drive all multiplexed onto one pin (102) and driven by a single driver circuit (117). In a diagnostics mode, the pin is connected to diagnostic equipment (106). When a diagnostic test has been completed, a tachometer drive signal is output on the pin, the drive signal having a duty cycle set high enough to illuminate the warning lamp (103) if a fault condition is detected by on-board sensors (112, 113). By combining multiple functions onto a single pin with a single driver circuit, the cost of implementing an engine control unit may be reduced compared with existing arrangements which require separate pins and drivers for each function.

摘要： A controller (20; 21; 22) used to control a flyback switching mode power supply (10; 11; 12). The flyback switching mode power supply (10; 11; 12) is constructed to charge a capacitor (C), and includes a rectifying device (RD), a series arrangement of a switch (SW1) and a primary winding (L1) of a transformer (T) for receiving an input voltage (Vin), and a secondary winding (L2) of the transformer (T) for charging the capacitor (C) via the rectifying device (RD) to an output voltage (Vout). The controller (20; 21; 22) is configured to sense the output voltage (Vout) and to turn on the switch (SW1) when the change of the output voltage (Vout) over time becomes smaller than a predetermined threshold (dth). By using the controller (20; 21; 22) to sense and use the output voltage (Vout) across the capacitor (C) to turn on the switch (SW1), a controlled flyback switching mode power supply (10; 11; 12) that makes use of voltage control is realized.
