MOSFET transistor 700 V | TOPSwitch-HX

power

TOPSwitch-HX 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. Lower System Cost, Higher Design Flexibility Multi-mode operation maximizes efficiency at all loads New eSIP-7C and eSIP-7F packages build on PIs experience with high power and high reliability packages No heatsink required up to 35 W (up to 48 W at 230 VAC) using P, G or M packages Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset 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 packages) reduces transformer and power supply size (half frequency option for video applications) Tight I2f parameter tolerance reduces system cost Frequency jittering reduces EMI filter cost Heatsink is connected to SOURCE for low EMI Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions Accurate hysteretic thermal shutdown function automatically recovers without requiring a reset Fully integrated soft-start for minimum start-up stress Extended creepage between DRAIN and all other pins improves field reliability
