Power supply with PWM controller, method for operating a power supply for generating a supply voltage and an output voltage and a power adapter.

摘要

Power supply (1) with a power input (2) and to a load output (9) adjacent the output voltage (Vout) of the power supply (1), a PWM controller (6) with a PWM input (10), a PWM output ( 11) and a supply input (12), the normal conditions of use of the AC adapter (2) the voltage (V6) at the PWM output (11) of the PWM controller (6) and the output voltage (Vout) of the power supply (1) the same voltage level exhibit. The advantage of this type of power supply, the high efficiency at low output voltages. Such power supplies are preferably used in standby circuits.
