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
