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.
The AP3106 integrates a lot of functions such as the
Lead-Edge Blanking (LEB) of the current sensing,
internal slope compensation, line compensation, and
several protection features that include
cycle-by-cycle current limit (OCP), over voltage
protection, OTP, OLP and brownout protection.
The AP3106 is available in SOIC-7 package to
realize a compact size.
