Lower System Cost, Higher Design Flexibility
►Multi-mode operation maximizes effi ciency at all loads
►New eSIP-7F and eSIP-7C packages
► Low thermal impedance junction-to-case
(2 °C per watt)
►Low height is ideal for adapters where space is limited
►Simple mounting using a clip to aid low cost manufacturing
►Horizontal eSIP-7F package ideal for ultra low height adapter and monitor applications
►Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink
►No heatsink required up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC
►Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
►Allows both primary and secondary sensing
►Line undervoltage (UV) detection prevents turn-off glitches
►Line overvoltage (OV) shutdown extends line surge limit
►Accurate programmable current limit
►Optimized line feed-forward for line ripple rejection
►132 kHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size
► Half frequency option for video applications
►Frequency jittering reduces EMI fi lter cost
