摘要： A voltage-waveform detector produces a voltage-feedback signal and a discharge-time signal by multi-sampling a voltage signal of a transformer. The discharge-time signal represents a discharge time of a secondary-side switching current. A voltage-loop error amplifier amplifies the voltage-feedback signal and generates a control signal. An off-time modulator generates a discharge-current signal and a standby signal in response to the control signal and an under-voltage signal indicating a low supply voltage of the controller. An oscillator produces a pulse signal determining the off-time of the switching signal in response to the discharge-current signal. A PWM circuit generates the switching signal in response to the pulse signal and the standby signal. The standby signal further controls the off-time of the switching signal and maintains a minimum switching frequency.

摘要： The invention disclosed relates to methods and apparatuses to trim current limit (I p ) and frequency (f) to maintain a constant maximum power. In one aspect of the invention, a power supply regulator (321) having a peak current limit detection threshold and an operating frequency is disclosed. The peak current limit threshold or the operating frequency are adjusted specifically to maintain the 1 p m f n product substantially constant from one power supply controller to another where m is substantially equal to 2 and n is substantially equal to 1. In another aspect of the invention, the power supply regulator has a control circuit having a control threshold current.
The peak current limit threshold or the operating frequency are adjusted specifically to maintain the product of 1 p m f n divided by the control threshold current substantially constant from one power supply controller to another where m is substantially equal to 2 and n is substantially equal to 1.

摘要： The invention concerns an arrangement for the galvanically isolated transmission of auxiliary power (direct voltage) and information to an electronic unit with a switched mode power supply comprising a translator in which the primary winding can be connected to a direct voltage by means of a switching arrangement which can be actuated by a control circuit. According to the invention, in order to be able to produce such an arrangement comparatively cheaply, the control circuit (9) is designed such that it actuates the switching arrangement (7) according to information (I1) to be transmitted to the secondary side of the switched mode power supply (4). An evaluation circuit (14) which detects the primary information (I1) is connected to a point of the circuit between the secondary winding (w2) of the translator (6) and the conventional rectifier element (10). Provided on the secondary side of the switched mode power supply (4) is a transmitter (18) which switches the load of the secondary winding (w2) to low impedance according to information (secondary information (I2)) to be transmitted to the primary side (2) of the switched mode power supply (4) when the circuit arrangement is open; one end (E) of the primary winding (w1) is connected to an evaluation component (23) which detects the secondary information (I2).
