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.

Features

• Green-mode PWM Control

• Low Start-Up Current (Typ. 14uA)

• Low Operating Current (Typ. 4mA)

• Programmable PWM frequency with Frequency Jittering

• Peak-current-mode Control

• Cycle-by-Cycle Current Limiting

• Synchronized Slope Compensation

• Leading-Edge Blanking

• Constant Output Power Limit

• Totem Pole Output with Soft Driving

• VDD Over Voltage Protection (OVP)

• 150°C OTP with Hysteresis

• Internal Latch Circuit (OVP, OTP)

• Internal Open-loop Protection

• VDD Under-voltage Lockout (UVLO)

• GATE Output Maximum Voltage Clamp (18V)

Applications

• Notebook Power Adapters

• DVD-P, STB, LCD Monitor Power

• Open-Frame SMPS
