IK3401 - Green Mode PWM Controller

General 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.

Key Features

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 the power supply to easily meet international power conservation requirements. To further reduce power consumption, IK3401 is www.DataSheet4U.com manufactured by using the HV-CMOS process. This allows the lowest start-up current around 14uA, and the operating current is only 4mA.
