Оффлайн AC/DC переключатель, TOPSwitch-HX, обратноходовой, 85В - 265В AC, 66кГц, 2.08А выход, 62Вт

The TOP254EN is an enhanced EcoSmart™ Integrated Offline Switcher with advanced feature set and extended power range. TOPSwitch-HX incorporates a 700V power MOSFET and high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device. TOPSwitch-HX is an integrated switched mode power supply chip that converts a current at the control input to a duty cycle at the open drain output of a high voltage power MOSFET. It features the high voltage start-up, the cycle-by-cycle current limiting, loop compensation circuitry, auto-restart and thermal shutdown, the TOPSwitch-HX incorporates many additional functions that reduce system cost, increase power supply performance and design flexibility. A patented high voltage CMOS technology allows both the high-voltage power MOSFET and all the low voltage control circuitry to be effectively integrated onto a single monolithic chip.
  • Multi-mode operation maximizes efficiency at all loads
  • Low thermal impedance junction-to-case
  • Low height is ideal for adapters where space is limited
  • Simple mounting using a clip to aid low manufacturing
  • Output overvoltage protection is user programmable for latching/non-latching shutdown with AC reset
  • Allows both primary and secondary sensing
  • Line undervoltage detection prevents turn-OFF glitches
  • Line overvoltage shutdown extends line surge limit
  • Accurate programmable current limit
  • Optimized line feed-forward for line ripple rejection
  • Frequency jittering reduces EMI filter
  • Heat sink is connected to SOURCE for low EMI
  • 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
  • Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
  • 132kHz Frequency reduces transformer and power supply size
