TECHNICAL DATA Green Mode PWM Controller Description The IK3401 is a green mode PWM controller. It is specially designed for DVDP, STB and LCD monitor application. To minimize standby power consumption, a green-mode function provides off-time modulation to continuously decrease the switching frequency at light-load conditions. Under zero-load conditions, the power supply enters burstmode. To avoid acoustic noise problem, the minimum PWM frequency set above 20KHz. This green-mode function enables
