BCDSEMI AP3106MTR-G1

Preliminary Datasheet
HIGH VOLTAGE GREEN MODE PWM CONTROLLER
General Description
Features
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.

Current sense pin. Connect it to sense the MOSFET current
Supply voltage pin
Connect this pin to positive terminal of bulk capacitor to provide the
startup current for the controller. When VCC voltage reachs UVLO
(on), this HV loop will be turned off to save the power loss of the
startup circuit
