Highly Integrated Solution
• Eliminates up to 50 external components–saves space, cost
• Integrates 220 V high frequency MOSFET, PWM control
• Lower cost plastic DIP surface mount (G package) and
through-hole (P package) options for designs ≤35 W
• Thermally efficient TO-263-7C (R package) option for high
power applications
Superior Performance and Flexibility
• Eliminates all external current sensing circuitry
• Built-in auto-restart for output overload/open loop protection
• Pin selectable 300/400 kHz fixed frequency
• Wide input (line) voltage range: 16-75 VDC
• Externally programmable current limit
• Source connected tab reduces EMI
• Line undervoltage (UV) detection: meets ETSI standards
• Line overvoltage (OV) shutdown protection
• UV/OV limits gate drive voltage for synchronous rectification
• Fully integrated soft-start for minimum stress/overshoot
• Supports forward or flyback topology
• Cycle skipping: regulation to zero load without pre-load
• Hysteretic thermal shutdown for automatic fault recovery
• RoHS compliant P and G package options
EcoSmart™– Energy Efficient
• Extremely low consumption at no-load
• Cycle skipping at light load for high standby efficiency
Applications
• PoE applications, VoIP phones, WLAN, security cameras
• Telco central office equipment: xDSL, ISDN, PABX
• Distributed power architectures (24 V/48 V bus)
• Industrial controls
