HIGH VOLTAGE GREEN MODE PWM CONTROLLER
Description
The AP3107Z is the high voltage start-up, current mode PWM
controller with green mode power-saving operation.
To minimize the standby power consumption, a proprietary adaptive
green mode function provides frequency modulation at light load
conditions. To avoid acoustic noise problems, the minimum PWM
frequency is set at about 26kHz.
The AP3107Z features proprietary frequency dithering function
internally that helps to reduce EMI emission of a power supply with
minimum line filters used.
The AP3107Z also integrates a lot of functions such as Leading-Edge
Blanking (LEB) of the current sensing, internal slope compensation,
line compensation and several protection features. The protection
functions include cycle-by-cycle current limit (OCP), over voltage
protection, OTP, OLP and brownout protection.
The AP3107Z is available in SO-7 package.
