TOP258PN Datasheet

AC/DC Switching Converters Off-Line Switcher


TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device. TOP258PN Features &bull; Multi-mode operation maximizes effi ciency at all loads&bull; New eSIP-7F and eSIP-7C packages - Low thermal impedance junction-to-case (2 &deg;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&bull; Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink&bull; 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&bull; Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset&bull; Allows both primary and secondary sensing&bull; Line undervoltage (UV) detection prevents turn-off glitches&bull; Line overvoltage (OV) shutdown extends line surge limit&bull; Accurate programmable current limit&bull; Optimized line feed-forward for line ripple rejection&bull; 132 kHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size &bull; Half frequency option for video applications&bull; Frequency jittering reduces EMI fi lter cost&bull; Heatsink is connected to SOURCE for low EMI&bull; Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions&bull; Accurate hysteretic thermal shutdown function automatically recovers without requiring a reset&bull; Fully integrated soft-start for minimum start-up stress&bull; Extended creepage between DRAIN and all other pins improves fi eld reliability
