Power Integrations introduces the TOPSwitch®-HX integrated power supply control IC. With its high level of integration and robust feature set, TOPSwitch-HX enables simple, cost saving, flexible designs with up to 50 less components than competing discrete and integrated solutions. TOPSwitch-HX features a 700V MOSFET alongside low-voltage control circuitry on a monolithic IC. Other features include integrated auto-restart, adjustable current limit, input under-voltage and output over-voltage protection, hysteretic thermal shutdown, and frequency jittering to minimize EMI.
