• Under 50mW Standby Power Consumption at 265VAC, No-load Condition with Burst Mode
• Precision Fixed Operating Frequency with Frequency Modulation for Attenuating EMI
• Internal Startup Circuit
• Built-in Soft-Start: 20ms
• Pulse-by-Pulse Current Limiting
• Various Protections: Over-Voltage Protection (OVP), Overload Protection (OLP), Output-Short Protection (OSP), Abnormal Over-Current Protection (AOCP), Internal
Thermal Shutdown Function with Hysteresis (TSD)
• Auto-Restart Mode
• Under-Voltage Lockout (UVLO)
• Low Operating Current: 1.8mA
• Adjustable Peak Current LimitApplications
• SMPS for VCR, STB, DVD, & DVCD Players
• SMPS for Home Appliance
• Adapter
