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
