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
