Preliminary Datasheet
HIGH VOLTAGE GREEN MODE PWM CONTROLLER AP3106
General Description
The AP3106 is a high voltage start-up, current mode PWM controller with green-mode power-saving operation.
The PWM switching frequency at normal operation is externally programmable and trimmed to a narrow range.
The AP3106 integrates a proprietary internal frequency dithering function that helps to reduce EMI emission of a power supply with minimum line filters used.
To minimize the standby power consumption, a proprietary adaptive green-mode function is available to implement frequency modulation under light-load conditions. To avoid acoustic noise problems, the minimum PWM frequency is set at about 26kHz.
