Lower System Cost， Higher Design Flexibility ? Multi-mode operation maximizes efficiency 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 heat sink 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 filter cost
