Description
The FSDM0565R is an integrated Pulse Width Modulator (PWM) and Sense FET specifically designed for high
performance offline Switch Mode Power Supplies (SMPS) with minimal external components. This device is an
integrated high voltage power switching regulator which combine an avalanche rugged Sense FET with a current mode PWM control block.

FEATUREs
• Internal Avalanche Rugged Sense FET
• Advanced Burst-Mode operation consumes under 1 W at 240VAC & 0.5W load
• Precision Fixed Operating Frequency (66kHz)
• Internal Start-up Circuit
• Pulse by Pulse Current Limiting
• Abnormal Over Current Protection (AOCP)
• Over Voltage Protection (OVP)
• Over Load Protection (OLP)
• Internal Thermal Shutdown Function (TSD)
• Auto-Restart Mode
• Under Voltage Lock Out (UVLO) with hysteresis
• Low Operating Current (2.5mA)
• Built-in Soft Start

APPLICATION
• SMPS for LCD monitor and STB
• Adaptor
